Abstract
This Study focuses upon an aspect of how living organisms and humans in particular can be adversely affected by highly coherent electromagnetic fields of technological origin, in a way that is not entertained or addressed by existing Safety Guidelines – namely, through the possibility of non-thermal, frequency-specific influences of an informational nature. Supporting evidence is presented, and attention drawn to a disturbing consistency between some of these influences and the nature of certain adverse health effects found amongst some exposed people. On the basis of a detailed analysis of the present situation, a number of recommendations are made to promote a higher degree of electromagnetic biocompatibility between these fields and the living human organism than currently obtains.

OPTIONS BRIEF
1. Policy options for the European Parliament
·
the non-emergency prolonged use of mobile phones by children – and
particularly pre-adolescents – be strongly discouraged, on account of their
increased vulnerability to any potential adverse health effects.
·
the
mobile phone industry refrain from promoting prolonged use of mobile phones by
children by the use of advertising tactics exploiting peer pressure and other
strategies to which the young are susceptible, such as the (now discontinued)
use of DISNEY character fascias on the phones.
·
the mobile phone industry make it clear to the consumer that the
specific absorption rate (SAR) -
which in some countries is shortly to be declared on the handset - refers only to the degree to which the
microwave emissions from the antenna can heat biological tissue, and is in no way relevant to non-thermal effects that the emissions from a mobile phone may have
on the user.
·
The efficacy of devices such as shields and ear-pieces be indicated on
the basis of biological tests, and
not solely on the reduction in SAR
value (as determined by the use of a ‘phantom’ head) that their use might
achieve.
b) It be made clear to the consumer that
such devices afford no protection against the low frequency pulsed magnetic
field from the battery of the phone.
·
concerning personal protection devices claiming to boost the immunity of the user against any
adverse impacts of exposure (including those from the battery magnetic field):
a) The efficacy of such devices be
established by biological testing.
b) Such devices not be rejected (as has
occurred in certain consumer surveys that have been published) solely on the
grounds that their use does not reduce SAR,
as measured using a ‘phantom’ head; for this is not what they are designed to
do.
Accordingly, the SAR
is here a fundamentally inappropriate
measure against which to assess their efficacy.
2. Policy options for the European Commission
·
Future
EU-sponsored research should incorporate the following recommendations:
a) living systems under investigation be exposed to the
emissions of an actual mobile phone, rather than a ‘surrogate’, since the
emissions have a quite different biological impact, in consequence of certain
pulse frequency differences.
b) in assessing
the significance to humans of results obtained using animals, particular
attention be paid to differences in exposure conditions, such as whether
exposure is size-resonant, whether it is to the near or far field of the
antenna, and whether whole-body or more localised exposure occurs.
c) systematic investigation be made into the influence
of different kinds of pulsing (of real phones) on the human EEG, and ideally on the MEG, and of whether any observed changes
in power spectra are correlated with changes in the level of deterministic
chaos.
d) use be made of novel, non-invasive technologies,
such as biophoton emission, to investigate the influence of mobile phone
radiation on living systems.
e) in assessing the effects of mobile phone radiation
more attention be paid to lessons that have been learnt from exposure to other
kinds of related radio frequency fields, such as those from the Skrunda,
military and police radars.
f) in the light of reports of cattle being quite
seriously adversely affected at farms where there is a base-station, a
veterinary monitoring service be established to collect and analyse such
reports, and raise awareness amongst farmers of this potential hazard to their
livestock.
·
attempts
be made – perhaps under the aegis of national regulatory bodies - to increase
awareness of the electromagnetic nature of living organisms and their
consequent hypersensitivity to coherent, ultraweak electromagnetic signals.
[Until this is achieved, the need to extend thermally-based safety guidelines,
by incorporating electromagnetic
biocompatibility, is unlikely to be accepted.]
3. Technological options at the operational level
Whilst the
question of precisely how adverse
health effects can be provoked by non-thermal influences of the pulsed
microwave radiation currently employed in GSM
telecommunication, as well as those from ELF
fields associated with other technologies, is far from resolved, the
circumstantial evidence consistent with such influences suggests at least two
ways in which biocompatibility with this technology could be enhanced by
changes involving the fields alone:
·
In the
case of exposure to GSM radiation, reduce intensities to the level below which
no adverse effects have been empirically found in exposed populations, bearing
in mind that there are indications of non-thermal thresholds for biological
effects of the order of a microwatt/cm2. Power densities a few tenths of this value are common at distances of 150-200m from a
typical 15m high Base-station mast and within the range of the more localised
side-lobes in the immediate vicinity of a mast - adverse effects being reported at both locations. Incorporating a further safety factor of 10
indicates that, at locations where there is any long-term exposure, power
densities should not exceed 10 nanoW/cm2.
[To appeal to the (alleged) absence of health problems associated with
the higher power density electromagnetic fields emitted by radio/TV
transmitters in an attempt to justify the retention of the present level of
emission from GSM Base-stations is untenable, on at least two accounts: (i) the
nature of the emissions are quite different, with respect to carrier
frequencies, modes of transmission (pulsed/analogue), and beam morphology, (ii)
there are health problems connected with some such transmitters, contrary to
what is often claimed!]
·
Ensure
that there are no ELF frequencies –
either of amplitude modulation (including pulsing, as the extreme case) of RF fields, or of other electric
/magnetic fields - in the range of human electrical brain-wave activity, or
windows of calcium efflux.
[In the case of exposure to GSM radiation, this will be achieved, to a
certain extent, with the advent of the Third Generation of mobile phones (UMTS)
that utilise CDMA in place of TDMA. For
although any sensitivity to the microwave carrier will remain, the pulsing used
in CDMA is irregular; accordingly, CDMA radiation cannot enjoy the same
‘oscillatory similitude’ with the human brain-wave activity and electrochemical
processes as does TDMA. In consequence,
however, of the somewhat higher carrier frequency used, which is closer to
where water strongly absorbs microwaves, thermal effects could here become more
of a problem, particularly in view of the somewhat higher powers at which they
operate! The introduction of TETRA, on
the other hand, gives rise to an increased level of both thermal and
non-thermal concern.]
A major
contemporary threat to the health of Society is man-made ‘electrosmog’. This non-ionising electromagnetic pollution
of technological origin is particularly insidious, in that it escapes detection
by the senses – a circumstance which tends to promote a rather cavalier attitude regarding personal protection. Yet the nature of the pollution is such that
there is literally ‘nowhere to hide’.
Furthermore, given the relatively short time for which humanity has been
exposed to it, we have no evolutionary immunity either against any adverse
effects it might directly have on our bodies or against possible interference
with natural electromagnetic processes, upon which homeostasis appears to
depend, for example, the Schumann resonance – a weak electromagnetic field that
oscillates resonantly in the cavity between the earth’s surface and the
ionosphere at frequencies close to those of human brain rhythms, isolation from
which has been found to damage human health.
What
distinguishes technologically produced electromagnetic fields from most natural
ones is their much higher degree of coherence. This means that their frequencies are particularly well-defined,
and therefore more easily discerned by living organisms, including humans. This greatly increases their biological
potency, and ‘opens the door’ to the possibility of frequency-specific, non-thermal influences of various kinds,
against which existing Safety Guidelines – such as those issued by the
International Commission for Non-ionising Radiation Protection (ICNIRP) - afford no protection.
The Safety
Guidelines are based solely on consideration of the ability of radio frequency
(RF) and microwave radiation to heat
tissue, and of extremely low frequency (ELF)
magnetic fields to induce circulating electric currents in the interior of the
body, both of which are known to be damaging to health, if excessive. Since the severity of these effects
increases with the strength (intensity) of the fields in question, it is this
that the Guidelines restrict, the frequency of the fields being taken into
account only in so far as it affects
(through ‘size’ resonance effects) the ability of the organism to absorb energy
from the irradiating field and heat up accordingly.
The Guidelines
thus do not protect against adverse health effects provoked primarily and specifically through influences that the frequency of the fields might have on the human body.
A necessary
condition for such an influence is the existence in the organism of the
biological counterpart of an electrically tuned circuit – i.e. an endogenous oscillatory electrical activity.
In this case
the organism will respond - in a way akin to a radio - if the frequency of the
external field (either of the carrier wave, or of lower frequency amplitude
modulations/ pulsings) matches or is close to that of its tuned circuit.
This could
result in either an undesirably high resonant amplification of, or damaging
interference with, the associated endogenous biological activity.
These
influences can be considered to arise from a transfer of information (in a generalised sense) from the field to a living
organism, in that the organism is able, through this kind of ‘oscillatory
similitude’, to recognise – and in turn respond to – a feature of the external
field other than its intensity.
Equally
important is that the external electromagnetic fields be sufficiently coherent
to be discernible by the body against the level of its own incoherent thermal
emission at physiological temperatures.
Whilst this is usually the case, it should be noted that since the
radiation is not perfectly coherent, the occurrence of non-thermal effects is
still contingent upon a certain minimum intensity threshold, the magnitude of
which is, however, well below that at which any discernible heating occurs.
A good example
of such an ‘informational’, frequency-specific, non-thermal electromagnetic
influence on the living organism is the ability of a light flashing at a
certain rate to trigger seizures in people suffering from photosensitive
epilepsy. This is primarily due, not to
the brightness (intensity) of the light, but rather to the frequency of the
flash – which, if close to the frequency of the electrical brain activity
involved in epileptic seizures, can trigger their occurrence - i.e. the phenomenon is primarily a
frequency-specific effect of information transfer from the light to the brain,
the brain being able to ‘recognise’ the light by the rate at which it
flashes.
Existing
intensity-based Safety Guidelines (relating to the visible part of the
electromagnetic spectrum) afford no protection against such a non-thermal
effect, unless set so low that the light is not visible!
Some
oscillatory endogenous electrical activities of the living human body are quite
familiar - such as those of the heart and brain, which can be monitored by an electrocardiogram
and electroencephalogram, respectively. Equally familiar is the circadian
rhythm.
Others, - such
as the coherent electrical excitations at the cellular level whose frequencies
typically lie in the microwave region
of the electromagnetic spectrum, and those pertaining to crucially important
biochemical activities, involving, for example, the transport of calcium ions
across cell membranes - are somewhat less well-known.
Until the
frequency/information dimension of non-visible
electromagnetic radiation (microwaves and other non-propagating electric and
magnetic fields such as those from overhead power lines) - is recognised in its own right, these fields will constitute a potential threat to all living
organisms.
Since
electromagnetic fields are indispensable to
technology that Society is reluctant to abandon, more comprehensive protection should be
developed. As explained, we are currently
vulnerable to adverse health effects that might be provoked by
non-thermal effects of the frequency dimension, which escapes regulation by the
existing intensity-based Safety Guidelines.
Unlike
intensity, the frequency aspect of the problem cannot be addressed without
interfering with the frequency characteristics and informational content of the
aggressing field (the integrity of which must,
of course, be maintained in communication technologies, such as GSM telephony). We need therefore to
consider strategies that do not target the field, but rather the person being
irradiated, and devise ways to provide a higher degree of immunity than at
present.
Such strategies
are currently under development, and a number of related protection devices are
already available commercially, although often their efficacy has not always
been adequately demonstrated. (There is
an obvious parallel here with the pharmacological strategy of attempting to
protect against bacterial infection by taking vitamin C, for example, to fortify the immune system, rather than wearing a
protective mask to simply reduce the intensity of the bacterial field to which
the person is exposed.)
The competence
of existing Safety Guidelines could be broadened by extending the familiar
consideration of electromagnetic compatibility (EMC) between electromagnetic radiation and electronic
instrumentation to the living human
organism, as an electromagnetic instrument itself, par excellence. An
ambitious programme of electromagnetic biocompatibility is an
important task for the 21st century, and one that is shirked only at
our peril.
There is
currently much public concern over
possible adverse health effects provoked by long or short term exposure
to electrosmog. This concern focuses especially on overhead power lines and GSM
telephony. Quite justifiably, the
public remains sceptical of attempts at reassurance by government and industry,
particularly given the unethical way in which they often operate symbiotically
so as to promote vested interests, often under the brokerage of the regulatory bodies whose function it
supposedly is to ensure that the safety of the public is not compromised by electromagnetic exposure!
Given recent
experience with official duplicity over BSE/CJD
– with the initial assurances of no risk and subsequent revelations of
cover-ups - the public is now understandably wary of safety assurances from
‘official’ government scientific sources w.r.t. electromagnetic pollution. This
scepticism is enhanced when views contrary to
official perceived wisdom is, at worst silenced or, at best, studiously
ignored.
Public scepticism
is further exacerbated by reports of research supported financially by the
Mobile Phone Industry and of its attempts to ‘persuade’ those whose findings
might damage market development to
actually alter their results to make them more ‘market friendly’.
There is
currently an attempt (under the aegis of the World Health Organisation) to
globally ‘harmonise’ exposure standards, by persuading countries with more
stringent limits – such as Russia and China - to relax them in favour of the
higher levels tolerated in the West.
It can be no
coincidence that in Russia, where the frequency-specific sensitivity of living
organisms to ultra-low intensity microwave radiation was first discovered over
30 years ago, that the exposure guidelines (even if applied in theory, rather
than in practice) are still 100 times more stringent that those of ICNIRP!
There is a
regrettable tendency to attribute market–friendly research a greater
significance, publicity and profile than non-market friendly research, which suggest
the possibility of adverse health impacts.
An example of this is provided by the recent publication of a USA
epidemiological study, in which the statistically significant finding of an
elevated risk amongst users of mobile phones of the incidence of a rare kind of
tumour (epithelial neuroma) in the periphery of the brain – precisely where there is maximum penetration
of radiation from the mobile phone (the laterality of which also correlated
with phone usage) - was glossed over
and completely escaped the attention of the media, who focused instead
on the finding that there was no overall increase in the incidence of
brain tumours amongst mobile phone users.
The mainstream
scientific approach to assessing the harm of human exposure to electromagnetic
fields is guided by an essentially linear
perception, which might well be adequate to deal with thermal effects, but
is inappropriate for realistic
consideration of the non-thermal, frequency-specific vulnerability of the
living organism to the rather coherent electromagnetic fields.
In contrast to
thermal effects, non-thermal influence necessarily depends on the state of the
organism when it is exposed.This of course varies not only between different individuals, but also for the same individual, depending on his/her condition at the time of
exposure – i.e. such influences are
inherently non-linear in nature. As such, they often appear bizarre from a
linear standpoint. In addition, difficulties in independently replicating in
experiments tends to lead to their dismissal.
Attempts to address a problem that is
inherently non-linear from a linear perspective only exacerbate things:
outdated knowledge is worse than ignorance - at least the ignorant know what
they do not know!
In the case of
the mobile phone issue, not only has there been a reluctance on the part of
official bodies to grasp this non-linear ‘nettle’, but a lamentable failure to
pay attention to indications of the
harm to humans and animals caused by exposure to pulsed microwave fields of
sub-thermal intensity that have been long available from experience with
microwave installations (not least military ones) similar to those used in GSM telephony.
It is not so
much that, in the haste to make this new and valuable technology available,
the necessary safety research has been
bypassed or compromised, but rather - and more reprehensibly - that already
available indications that the technology is potentially less than safe have
been, and continue to be, studiously
ignored, both by the industry and by national and international regulatory
bodies.
A good example
of this is afforded by the conduct of the UK National Radiological Protection
Board, which was ‘unable’ to provide the Independent Expert Group on Mobile
Phones (IEGMP) - for whom they were
acting as the Secretariat - with certain highly relevant published papers, on
the grounds that they could not ‘find’ them, despite having been provided with
the full references by at least two individuals who gave evidence to the IEGMP, and curiously having had no
difficulty in providing less significant papers from the same issue of the journal!
The concern of
the public is thus not unfounded, and the irony of the present situation w.r.t
mobile phones and base-stations is that
current Safety Guidelines afford greater protection to electronic
instrumentation than they do to human beings!
There is a lack
of expert consensus on the significance
and credibility of research into biological effects of GSM-type radiation
and possible adverse health reactions
in susceptible people (despite many consistent, anecdotal positive reports).
It is probably
true to say that if the same lack of concensus and level of concern surrounded
a new drug or foodstuff, it would never be licensed.
Of particular
concern to the public – and generating
the most outrage – is the involuntary subjection of certain groups of the
population 24 hours/day, 7 days/week to the emissions of GSM base-stations, when they are insensitively sited near to homes,
schools and hospitals. The environment
of these people is permanently and
unavoidably polluted.This is a totally unacceptable state of affairs, which
raises serious ethical questions, and arguably contravenes the Nuremberg Code,
in that it is these people who will eventually reveal the degree to which
chronic exposure to such fields is noxious – information that is not
currently available: in other words, they are effectively involuntary
subjects in a mass experiment.
This study
offers a perspective on the potential implications for human health of exposure
to the pulsed microwave radiation currently used in GSM telephony, which differs somewhat from that currently espoused
by mainstream science, but one that provides a much more holistic insight into
the essential elements of the problem.
Of particular
importance is the emphasis given to (i)
the fact that electromagnetic fields are not alien to living organisms, but
play a crucial role in controlling and maintaining their orderly functions – i.e. that a living organism is an
electromagnetic instrument of great and exquisite sensitivity.
(ii) the subjectiveness of human
vulnerability, which necessarily follows from the inherently non-linear nature
of the problem, which is here recognised ab
initio, and
(iii) the presence of ELF features both in the microwave
pulses emitted by the antenna of a mobile phone and in the (much more penetrating) magnetic field associated with
the surges of electric current from the battery of the handset, which are
necessary for the generation of the microwave pulses.
Indeed, it is
here suggested that it is precisely through the presence of these ELF features that the emissions of a GSM phone and other related
communication technologies, such as TETRA,
can influence brain function - notably, its electromagnetic activity
(brain-waves), its electrochemistry (including that of the neuroendocrine
system, particularly with respect to melatonin levels) and the permeability of
the blood-brain barrier, as well as altering cellular calcium ion concentrations. It is possible that this latter effect is
only one particular facet of a more general disruptive influence that ELF fields can have on the integrity of
essential ion-protein links (as suggested by recent Russian work) - an
influence that could well be relevant also to consideration of bio-negative
influences of exposure to other kinds
of electromagnetic fields, such the low frequency magnetic fields associated
with power lines and the mains appliances that they supply, which have been the
subject of controversy for a much longer time.
The Study is
structured as follows. Attention is
first drawn to the irrationality of the current situation that effectively affords – through electromagnetic
compatibility regulations (EMC) -
electronic instrumentation a higher level of protection against GSM radiation, for example, than do
existing Safety Guidelines governing human exposure, which protect only against
adverse health effects attributable to excessive heating, and not against those
that might be provoked in some people by the radiation’s non-thermal, frequency-specific interference with endogenous
electromagnetic activities essential for homeostasis.
To appreciate
this more fully, the study explains why GSM
signals are bio-active, and gives numerous examples of frequency specific,
non-thermal biological influences that the kind of radiation currently used in GSM telephony can exert on living organisms, including humans.
Difficulties
sometimes experienced in independent attempts to replicate these effects -
which are frequently used to discredit positive results, and to dismiss them as
artefacts of the particular experimental protocols used - are addressed, and
possible reasons for discrepant results identified. The relevance to humans of findings obtained using animals, such
as rats - which can be subject to exposure conditions that are quite different
from those experienced during mobile phone use – is discussed and, in the case
of human studies, the importance of exposing the subjects to the emissions of a
real mobile phone, rather than a ‘surrogate’, as is often done, is
stressed. Attention is then focused on
the reality of adverse health impacts of both human and animal exposure to GSM and similar radiation, including
that from military sources.
Although the
occurrence of non-thermal influences per
se does not, of course, necessarily entail adverse consequences for human
health, growing indications of a consistency between some of the published
non-thermal effects of GSM radiation
and the nature of certain reported adverse health effects, is cause for concern
- particularly the recent reports of an increased incidence in a rare kind of
brain tumour (notwithstanding the relatively short exposure time in comparison
with typical latency periods), which is consistent with the genotoxicity of the
radiation.
Reasons why
children must be considered potentially more at risk are identified, and arguably the most significant point - namely that not everyone is necessarily adversely affected - is addressed, as
also are the implications of this on the validity of the familiar claim that
there are no established adverse health effects of exposure to GSM radiation, provided its intensity
conforms to the limits set by existing Safety Guidelines, which, it is argued,
neglect the most discriminating feature of all – the fact that the object exposed is alive.

Part B: ARGUMENTS and
EVIDENCE
B-1. Introduction:
Electromagnetic Compatibility and Electromagnetic Bio-
incompatibility
The importance of ensuring compatibility between activated electronic instrumentation of various kinds and the pulsed microwave radiation currently used in GSM mobile telephony is well recognised and generally accepted. Prohibition of the use of cellular phones on aircraft and in hospitals, on the grounds that their emissions might adversely interfere with the operation of sensitive electronic equipment, is familiar, and their possible deleterious effect on personal medical devices, such as heart pacemakers, hearing aids, defibrillators and insulin pumps has been the subject of a number of published scientific studies in recent years. Given that it is inconceivable - at least in the case of aviation and hospital equipment - that the interference could arise from the heating effect of the radiation, some other, non-thermal, influence of the radiation must here (at least tacitly) be considered to be responsible. Unfortunately, however, the same considerations do not currently extend to the alive human organism, which is generally considered to be immune from adverse influences of GSM radiation, on account of its intensity1 being far too low to cause any deleterious degree of body tissue heating, as quantified through the so-called specific absorption rate, or SAR - the rate at which the external electromagnetic field deposits energy in unit mass of the body, averaged over a certain period of time; for, contrary to case of electronic instrumentation, it is generally believed that for humans adverse effects can arise only from excessive heating. Indeed, this belief is reflected in the relative leniency of the Safety Guidelines2 issued by the International Commission for Non-ionising Radiation Protection (ICNIRP), which permit humans to be exposed to electric fields that are over ten times stronger than the limit of 3V/m limit that is applicable to all electronic goods offered for sale in EU under current EMC legislation. on electromagnetic compatibility (EMC).
Despite the prevalence of this attitude - particularly amongst the various Regulatory Bodies, both national and international - it is not one that is universally held3, and the debate over the potential noxiousness of GSM radiation continues at both professional and public levels. What is so disturbing is if the same level of concern and uncertainty obtained in the case of a new food or drug, they would almost certainly never be licensed.
A good example of the prevailing disregard for what might be termed ‘electromagnetic biocompatibility’ is the development of TETRA (Trans European/or Terrestrial Enhanced Trunked Radio Access), which operates at somewhat higher powers than does GSM, and over a much wider range of microwave carrier frequencies. Most disturbing, however, is the fact that the basic frame repetition rate is here 17.6Hz. For this frequency (which lies in the range of beta brain-wave activity) is close both to that at which a flashing visible light can provoke seizures in people with photosensitive epilepsy4, and to the modulation frequency at which there is a maximum in the expression of calcium ions from brain cells when they are irradiated with amplitude modulated, low intensity RF radiation over a wide range of carrier frequencies5-7; it should be remembered that these ions play a crucial role in inter-cellular communication, any interference with which could well undermine the integrity of the whole nervous system, although the extent to which this actually occurs is, at present uncertain, owing to a lack of the necessary research. Furthermore, in consequence of the lower frequency band assigned to the emergency services (380MHz - 400MHz), the penetration of the radiation is here much greater than it is with GSM, facilitating its deeper access into the brain directly through the skull.
B-2. Why GSM Signals are Bio-active
That the low intensity, pulsed microwave radiation currently used in GSM telephony can exert subtle, non-thermal influences on the alive human organism arises, in the first place, because microwaves are, after all, waves, and, as such, have properties other than solely intensity. In particular, GSM radiation has certain rather well defined frequencies, which facilitate its discernment by the living organism, and via which the organism can, in turn, be affected. This is so because the alive human organism itself supports a variety of oscillatory electrical biological activities, each characterised by a particular frequency, some of which happen to be close to those used in GSM!
The particular frequencies utilised in GSM that must be anticipated to be particularly ‘bio-active’ are those of the microwave carrier (900/1800 MHz) and those associated with certain pulsings that characterise the signal employed in the Time Division Multiple Access (TDMA) strategy that is used in GSM - specifically, the multi-frame repetition rate of 8.34Hz, and the 2Hz periodicity associated with the discontinuous transmission (DTX) mode of the phone – an energy saving mode that becomes active when the user is listening but not speaking. For there is evidence8 that adequately metabolising systems themselves support highly organised, oscillatory electrical activities at the cellular level, whose frequencies generally lie in the microwave band, in terms of which the dramatic effects of ultra-low intensity microwaves of specific frequencies on processes as fundamental as cell division and intercellular communication can be understood in a rather natural way9. It should be noted that this endogenous microwave activity is a quite general (non-equilibrium) prediction of modern, non-linear biophysics10 for living systems, under appropriate metabolic conditions.
The two ELFs (at 8.34Hz and 2Hz), on the other hand, correspond to those found in the human EEG - specifically, in the ranges of the alpha and delta brain-waves, respectively.
In the case of a GSM mobile phone, these two ELFs are reinforced by those of the essentially unscreenable magnetic fields associated with the current surges from the battery of the phone that are necessary in order to endow the microwave emission with the pulse characteristics required for TDMA. Peak magnetic field strengths as high as 40mT have been measured near the back of one particular model of phone11, 12, the noxiousness of which is indicated by recent experiments13, 14 employing chick embryos, which reveal an increased degree of mortality when the phone is protected by a proprietary shielding device that reduces the microwave output. With the device in place, the increased (microwave) power output necessary to maintain contact with the base-station necessitates stronger surges of current, associated with which are correspondingly stronger (and evidently more noxious) ELF magnetic fields. These ELF magnetic fields could thus pose an even greater hazard to human health than do those associated with the microwave emission, a matter that warrants further experimental investigation. In this connection, mention should be made of recent theoretical advances15 in understanding, at the quantum level, the disruptive influence that ELF fields (including pulsed ones) can have on the integrity of essential ion-protein links, resulting in an imbalance of intra and inter cellular ion concentrations; this can result in metabolism malfunction and high levels of stress that can be lethal to organisms in the early stages of development. It should be noted these ideas are also relevant to consideration of bio-negative influences of exposure to other kinds of electromagnetic fields, such the low frequency magnetic fields associated with power lines and the mains appliances that they supply, which have been the subject of controversy for a much longer time.
B-3. Indications of
Non-thermal influences of Microwave Radiation, including GSM
3.1 In vitro and in vivo evidence
Much experimental evidence of non-thermal influences of microwave radiation on living systems has been published in the peer reviewed, scientific literature during the last 30 years – relating both to in vitro and in vivo studies - including some obtained more recently under exposure to radiation both from a real GSM phone; most often, however, an experimental ‘surrogate’ microwave generator is used, the emissions of which can differ in certain important ways, the importance of which is not generally recognised (see Section B-3.3). It should also be appreciated that the fields to which the investigative systems are exposed in some of the earlier work are even farther removed from GSM, both with respect carrier frequency, as well as CW/pulsed differences. A selection of some in vitro studies is given below in Table I.

Human in vivo studies, under GSM or similar conditions, include:
1) Effects on the human EEG, specifically, a delayed increase in spectral power density particularly in the alpha band42, which has been corroborated43 in the awake EEG of adults exposed to GSM radiation. Influences on the asleep EEG have been reported, including a shortening of rapid eye movement (REM) sleep44 (with possible adverse effects on learning) during which the power density in the alpha band again increases, and effects on non-REM sleep45. Exposure to mobile phone radiation also causes a significant decrease in the preparatory slow potentials in certain regions of the brain46, 47, and affects memory tasks48-50.
2) Observation of an increase in resting blood pressure during exposure51.
3) Observation of an increase in the concentration of nitric oxide in exhaled air correlated with mobile phone use, indicative of an elevated level of stress and inflammation52.
4) The established efficacy of Microwave Resonance Therapy53, 54 – i.e. the possibility of re-storing homeostasis in a wide variety of human pathological conditions by ultra-weak microwave irradiation at specific frequencies under carefully controlled clinical conditions - otherwise known as ‘quantum medicine’, in view of the fact that such low intensities are used that individual quanta are involved. The existence of such positive effects of microwave irradiation makes it difficult to argue that such radiation can not have the opposite effect – i.e. a bio-negative one – when applied indiscriminately, and at higher intensities – in much the same way that the therapeutically beneficial effect of pharmaceutical drugs does not preclude the possibility of allergic drug reactions or, indeed, drug abuse.
Although, apart from in the latter case, the power density of the radiation used in these experiments is typically that found at the head when using a mobile phone, and thus much higher than that found in publicly accessible areas in the vicinity of a base-station, the information content of the radiation emitted by the latter is the same; accordingly, these results are not irrelevant to the consideration of potential adverse health effects associated with chronic exposure to base-station radiation.
3.2 Difficulties in
replication
It should be noted that difficulties sometimes experienced in attempts to independently replicate certain frequency-specific non-thermal effects are actually to be expected. For in consequence of the highly non-linear, non-equilibrium nature of living systems, even the slightest differences in the physiological state of the biosystems used, and in the conditions obtaining in a particular experiment can, in consequence of deterministic chaos, assume singular importance55.
Quite apart from this problem, however, discrepant results can often be traced to certain differences in experimental protocols that only become apparent upon close scrutiny. Examples of this can be found in the attempt56 to replicate the resonant influence of centimetre microwaves of sub-thermal intensity on cell division in the yeast S. cerevisiae found by Grundler et al.17, and the attempt by Malyapa et al.57 to replicate the increase in DNA breakage under low intensity microwave irradiation found by Lai and Singh37, 38.
In the case of the yeast experiments, several features can be identified that could well account for the differing results, such as differences in the phase of the cell cycle at which exposure occurred, the use of synchronised cells in one experiment but not in the other, and differences in the imaging systems used (real-time vs. non-time lapse) to monitor cell division.
In the case of the DNA experiments, whilst both groups used microwave radiation of the same frequency, they irradiated different systems (live rats vs. a cell line), and used very different assays to assess the DNA damage; in addition, the replication attempt did not separate the (positively charged) bound protein from the (negatively charged) DNA strands, thus obtaining much less migration in the electrophoresis field, which was also applied for a much shorter time than in the original experiment; both these features militate against the formation of the ‘comet’ tails used to assess the degree of fragmentation.
3.3 Relevance of
experiments to conditions realised in actual mobile phone usage
Quite apart from possible differences in the physiological states of the animals used in the original an replication experiments, it should not be overlooked that differences in irradiation conditions can also contribute to difficulties in achieving replication; in addition, they can also be a confounding factor in assessing the relevance of positive animal results to humans (as also, incidentally, can differences in the ratio of the duration of irradiation to the lifetime of the species in question.) Thus, for example, whereas, for humans, whole-body exposure is realised arise only in the case of a base-station, where ‘far-field’ conditions obtain, this is not necessarily so for animals, which, depending on their size, can be whole-body exposed to the near-field of a 900MHz phone antenna (or its experimental surrogate), the characteristics of which are quite different. In the case of humans, by contrast, use of a phone primarily results only in a rather localised exposure to the near-field of the antenna. A further factor to be remembered is that in many experiments, subjects are not exposed to the actual emission of an real GSM mobile phone, but rather to that of a ‘surrogate’ microwave generator whose the output can differ in certain crucial ways. For example, it may not even be pulsed, and even if it does so at the GSM frame repetition rate (217Hz), it most probably will not contain the (bioactive) multi-frame frequency of 8.34Hz, and certainly not the 2Hz that characterises the DTX mode.
B-4. Indications of
Non-thermal Adverse Health Impacts of Exposure to GSM and
similar microwave radiation
The popular belief that adverse health effects can be induced only by the heating effect of GSM radiation is a fallacy:
1. There is rather
consistent empirical, anecdotal evidence from many countries that the health of
some people is adversely affected in
various ways when they are exposed to this kind of radiation, despite its
intensity being well below existing safety limits based on consideration of the
SAR. It should be stressed that the anecdotal nature of many of the reported
health problems – such as headache, sleep disruption, impairment of short term
memory, nose bleeds and, more seriously, an increase in the frequency of
seizures in some children already suffering from epilepsy - does not constitute grounds for dismissing
them out of hand, as is so often advocated.
For given the paucity, to date, of systematic epidemiological studies
pertaining to this relatively recently introduced technology, such reports are
an indispensable source of information – a point acknowledged in last year’s
Report58 of the UK
Commons’ Select Committee, dealing with the question of mobile phones and
health.
2. More disturbingly, not withstanding the absence of any overall increase in the incidence of brain tumours amongst users of mobile phones (mainly analogue ones, it should be emphasised), a statistically significant increase (by a factor of between 2 and 3) in the incidence of a rather rare kind of tumour (epithelial neuroma) in the periphery of the brain - where the radiation has the greatest access - the laterality of which correlates with mobile phone use, has been found59 in an epidemiological study in the USA, as part of the WTR Programme60.
3. There is documented evidence 61, 62 that long-term (involuntary) exposure to microwave radiation of intensities intermediate between that realised near an active phone and that found in the vicinity of a base-station (but at somewhat different carrier frequencies than used in GSM) does causes serious illness, such as leukaemia and lymphoma, in certain exposed people. This is the conclusion reached by a relatively recent reanalysis of the Lilienfeld report on the Moscow US Embassy irradiation during the ‘cold’ war, based on information that only became fully available following the Freedom of Information Act, which reveals that the original verdict of no serious health effects was, in fact, a sanitised version of Lilienfeld’s findings, in which his statements of concern had been deliberately removed by the State Department.
4. A US Defence Intelligence Agency document63 dated March 1976, reviewing Soviet work on biological effects of non-thermal exposure to microwave and radiofrequency radiation makes interesting, but disturbing, reading. For not only have many of the effects there reported now been found in the case of exposure to GSM telephony radiation, but the following extract (which, incidentally, was eventually also removed) reveals a less known ‘dark side’ of the issue that is consistent with the Moscow Embassy affair, and one that presaged – as it turned out - the subsequent deployment of this kind of radiation in psychotonics and other forms of non-lethal microwave weaponry:
‘The
potential for the development of a number of antipersonnel applications is
suggested by the research published in the USSR, East Europe and the West. Sounds and possibly even words which appear
to be originating intracranially can be induced by signal modulation at very
low average power densities.
Combinations of frequencies and other signal characteristics to produce
other neurological effects may be feasible in several years. The possibility of inducing metabolic
disorders also suggested. Animal
experiments reported in the open literature have demonstrated the use of low level
microwave signals to produce death by heart seizure or by neurological
pathologies resulting from breaching of the blood-brain barrier’.
5. An invaluable indicator of the potential noxiousness of the pulsed microwave fields emitted by base-stations is the increasing number of reports - some published, some as yet anecdotal - of adverse effects on the health and well-being of various animal species, specifically cattle, dogs, birds and bees. In the case of the affected cattle reported in one particular study64, the cattle (which were found to line up, all facing away from the mast) displayed a variety of problems, including severely reduced milk yields, emaciation, spontaneous abortions, and still births. Especially relevant are the following facts: (i) the condition of the cattle was found to improve dramatically when they were removed to pastures well away from the mast, only to deteriorate again once they were brought back, (ii) the adverse effects appeared only after GSM microwave antennae had been erected on a tower that had formerly been used to transmit only (analogue) TV and radio signals, associated with which there had, in this case, been no evident health problems. It should be noted that this is not an isolated occurrence, similar problems with cattle being reported from elsewhere65. In the case of domestic canine pets, there are a number of anecdotal reports of their immune systems being adversely affected, again in a reversible way. Finally, there are reports of declines in bird and bee populations following the commissioning of new base-station masts.
It should be noted that the occurrence of adverse effects in animals is particularly significant, in that it indicates that the effects are real, and not psychosomatical, as is often claimed, in the case of humans exposure, by those who maintain that base-station radiation is harmless. Furthermore, given that animals are often more highly electrosensitive than are humans, the serious nature of the health problems they have manifested over such a relatively short period of time could well portend a correspondingly serious noxiousness in the case of long-term exposure of humans, and constitute a valuable early-warning system, similar to the ‘canary down the mine’!
6. It is of interest, and probably highly significant, to note that some of the same symptoms have been reported in epidemiological studies (involving animals and plant life, in addition to humans), connected, not with mobile phone base-stations, but with other kinds of installations operating at somewhat lower frequencies - specifically, a Short-wave radio transmitter66, and a radar67, the latter being at 154-162MHz, with a pulse repetition frequency of 24.4Hz - at locations where the intensity of the emitted radiation is comparable to that typically found at 150m from a base-station. Additional effects include:
i) Depressed nocturnal melatonin levels in cattle66.
ii) Less developed memory and attention span (as well as decreased endurance of their neuromuscular apparatus) of children68 living within a 20km radius of the radar, subject to a maximum exposure of 0.039mW/cm2.
iii) A six-fold increase in chromosome damage in cows69 exposed to a likely maximum intensity of 0.1mW/cm2.
(The cited field intensities are estimated from information on the electric field intensity as a function of distance from the radar installation, given in Ref. 70.)
In each case, the unexposed population to the rear of the beams constituted the control group.
7. At somewhat higher intensities, but still well below the exposure limits permitted by the ICNIRP Guidelines, is a 2-fold increase in the incidence of cancer amongst Polish military personnel, which has been revealed by a long term, on-going study71.
With respect to the apparent absence to date of such serious, life-threatening adverse effects in the case of human exposure to GSM base-station radiation, it should be noted that this is no guarantee of immunity against long-term (or chronic) exposure. For exposure to this kind of radiation is still in its ‘early days’ in comparison to the much longer (10-15 years) latency period of the kinds of cancers that might be initiated or promoted in certain people.
Partly responsible for the reluctance to accept the reality
of the underlying non-thermal effects is not only their often counter-intuitive
nature - as exemplified, for instance, by the fact that they often become more
marked as the strength of the irradiating field decreases - but also the difficulties sometimes experienced in
attempts to replicate them, as already mentioned in Section 3.2. On the other hand, the equal reluctance to
accept that they can provoke adverse health reactions in some people can be
attributed - at least in part - to a general lack of appreciation that electromagnetic
fields are not alien to an alive
organism, but actually play a rather fundamental and integral role in its
organisation and control, from the cellular level upwards72-74 - i.e.
that an alive organism is itself an
electromagnetic instrument of great and exquisite sensitivity, and, as such, is
just as vulnerable to being deleteriously interfered with (non-thermally) by
external electromagnetic fields as is an activated piece of electronic
equipment, (although in the latter case the influence of a given field is
always the same, unlike the situation
with an alive organism.)
B-5. From Non-thermal Effects to Adverse Health Effects
The hypersensitivity of the alive human organism to ultraweak microwave radiation is reflected in the ways in which this kind of radiation has been found to affect a wide variety of brain functions, as already noted in Section B-3.1 - such as electrical activity (EEG)42-50, electrochemistry5-7, 24-26, 36, and the permeability of the blood/brain barrier34, 35 - and to degrade the immune system13, 14, 27, 28. Although these effects do not necessarily entail adverse health consequences, there is an undeniable consistency75 between some of these non-thermal influences and the nature of many of the health problems reported, such as headache, sleep disruption, impairment of short term memory, and, more seriously, significant increases in the frequency of seizures in some epileptic children when exposed to base-station radiation, and of brain tumours amongst users of mobile phones; it must, however, be admitted that precisely how these influences actually provoke adverse health reactions is at present unclear. Thus, the reports of:
a) Headache are consistent with the fact that microwaves are known to non-thermally affect the dopamine–opiate system of the brain36 and to increase the permeability of the blood-brain barrier34-35, since both of these have been medically connected with headache77-82.
b) Sleep disruption are consistent with the effect of GSM radiation on rapid eye movement (REM) sleep44 and on melatonin levels13, 14 - the latter being found also epidemiologically, in the case of RF exposure66.
c) Memory impairment is consistent with the finding that microwave radiation targets the hippocampus16.
d) Since there is no reason to suppose that the seizure inducing ability of a flashing visible light does not extend83 to (invisible) microwave radiation (which can access the brain directly through the skull) flashing at a similarly low frequency, together with the fact that exposure to this kind of radiation is known to induce epileptic activity in certain animals33, reports84 of increased seizure activity in some children that already suffer from epilepsy are perhaps not surprising.
e) The statistically significant increase in the incidence of amongst users of mobile phones in the incidence of epithelial neuroma is consistent both with the genotoxicity of low intensity microwave radiation, as indicated by the increased number37-38 of DNA strand breaks85, the formation of chromosome aberrations and micronuclei in human blood31 (the latter being corroborated in the case of GSM radiation by the WTR Programme60), and with the promotional effect of GSM radiation in the case of transgenic mice that had been genetically engineered to have a predisposition to develop cancer39.
B-6. The Increased
Vulnerability of Pre-adolescent Children
Pre-adolescent children can be expected to be (potentially) more at risk than are adults - as recognised in the recently published Report86 of the UK Independent Expert Group on Mobile Phones - for the following reasons:
i) Absorption of microwaves of the frequency used in mobile telephony is greatest87 in an object about the size of a child’s head – the so-called ‘head resonance’ – whilst, in consequence of the thinner skull of a child, the penetration of the radiation into the brain is greater than in an adult.
ii) The still developing nervous system and associated brain-wave activity in a child (and particularly one that is epileptic) are more vulnerable to aggression by the pulses of microwaves used in GSM than is the case with a mature adult. This is because the multi-frame repetition frequency of 8.34Hz and the 2Hz pulsing that characterises the signal from a phone equipped with discontinuous transmission (DTX), lie in the range of the alpha and delta brain wave activities, respectively. The fact that these two particular electrical activities are constantly changing in a child until the age of about 12 years – when the delta-waves disappear and the alpha rhythm is finally stabilised – means that they must both be anticipated to be particularly vulnerable to interference from the GSM pulsing.
iii) The increased mitotic activity in the cells of developing children makes them more susceptible to genetic damage.
iv) A child’s immune system, whose efficiency is, in any case, degraded by radiation of the kind used in mobile telephony, is generally less robust than is that of an adult, so that the child less able to ‘cope’ with any adverse health effect provoked by (chronic) exposure to such radiation.
B-7. But Not Everyone is Adversely Affected
Because both the occurrence of the initial provoking non-thermal effect as well as the severity of any associated adverse health effect depend on aliveness, they necessarily depend on the physiological state of the organism when it is exposed to the radiation - i.e. non-thermal effects are non-linear effects. Accordingly, it is quite possible that exposure to a low intensity field can entail a seemingly disproportionately large (non-linear) response (or none at all), and vice versa (consistent with which is the familiar occurrence of ‘windows’ of response), quite unlike the situation with the predictable (linear) thermal effects.
Since the physiological state of different people cannot, however, be anticipated to be the same – depending as it does on factors such as the stability of an individual’s brain rhythms against interference or entrainment by the radiation, their already prevailing level of stress, and the robustness of their immune system – it follows that identical exposure to exactly the same radiation can entail quite different (non-thermal) responses in different people (or even in the same person, depending on his/her condition at the time of exposure88), quite unlike the case of active electronic instruments. This is, of course, consistent both with the fact that not every exposed person is adversely affected (as is also the case with smoking*, for example, …………………………………………………………………………………………………………
* In the case of smoking, it
is often claimed that the odds ratio is here much higher than it is in the case
of electromagnetic exposure; but this is necessarily
so, because the former compares heavy smokers with non-smokers, of whom
there is effectively no electromagnetic counterpart, everyone being unavoidably
at least lightly exposed.
where not all smokers get lung cancer!) and with the difficulties encountered in some laboratory attempts to replicate non-thermal effects, particularly under in vivo conditions. For depending on a person’s genetic predisposition, and the fact that stress is cumulative, it is quite possible that exposure to an electromagnetic field simply supplies the final contribution that raises a particular person’s level of stress above some critical value, thereby ‘triggering’ the manifestation of some pathology that is already in a well advanced state, but which, in the absence of any exposure, would have remained latent. On the other hand, as already mentioned in Section B-3.2, difficulties sometimes experienced in attempts to independently replicate certain frequency-specific non-thermal effects are actually to be expected, in consequence of the highly non-linear, non-equilibrium nature of living systems, whereby even the slightest differences in the physiological state of the biosystems used and in conditions obtaining in a particular experiment can, in consequence of deterministic chaos, assume singular importance.
Accordingly, the oft-repeated statement that ......‘There are no established adverse health effects of exposure to GSM radiation (of sub-thermal intensity)’....... is actually quite true, but, in view of the above, this is necessarily so, thus making the statement essentially vacuous. The more relevant consideration is whether there is an established risk to human health. It must be concluded that such a risk does indeed exist, but - in view of the above considerations- the actual number and identity of those at risk are necessarily unknown, a priori, although, for the reasons identified, children and highly stressed people - particularly those with already compromised immune systems (as well as those on certain prescribed psychoactive drugs) - must be considered more vulnerable.
For the Mobile Phone Industry, regulatory bodies and government to deny this risk is not only untenable, but also, more significantly, lays them open to the charge that they attempted to ‘shield the public from uncertainty.’89. There is nothing to be lost - and a lot to be gained - by frankly admitting the existence of this risk, albeit possibly only to a minority of the public, and, in accordance with the recommendations of the Stewart Report86, taking the necessary steps to minimise it, such as those specified in Part A
B-8. The Inadequacy
of Existing Safety Guidelines
Existing Safety Guidelines, based solely on consideration of the SAR, afford no protection against the frequency-specific90 effects that have been the subject of this Study, since they limit only the intensity of the microwave radiation sufficiently to ensure that tissue heating by absorption of energy from the microwaves is not in excess of what can be coped with by the body’s thermoregulatory mechanism, so that temperature homeostasis is not compromised. Furthermore, it must be appreciated that the aliveness of the organism here enters only in so far as it dictates the magnitude of the temperature rise above which adverse health effects set in, the heating itself occurring irrespective of whether the organism is alive or dead.
In justifying the exclusion of any non-thermal input into the formulation of their Safety Guidelines, ICNIRP conclude2:
…...‘Overall, the literature on athermal effects of amplitude modulated electromagnetic fields is so complex, the validity of the reported effects so poorly established, and the relevance of the effects to human health is so uncertain, that it is impossible to use this body of information as a basis for setting limits on human exposure to these fields.’
It is to be stressed that this is not equivalent to denying the existence of non-thermal influences of this kind of radiation, or their potential to provoke adverse health reactions - as is often maintained by the Mobile Phone Industry – but simply that in ICNIRP’s view (because for the reasons stated) such effects cannot be used as a basis for setting exposure limits. Let us consider each point in turn. As an example of the complexity of athermal (i.e. non-thermal) effects, the following statement appears in the paragraph preceding the one from which the above quotation is taken:
…..‘Interpretation of
several observed biological effects (of this kind of radiation) is complicated
by the apparent existence of ‘windows’ of response in both power and frequency
domains. There are no accepted models
that adequately explain this phenomenon, which challenges the traditional
concept of a monotonic relationship between the field intensity and the
severity of the resulting biological effects.’
An absence of such a monotonic (‘dose-response’) relationship is, however, actually to be expected, since one is dealing with living organisms whose very aliveness means that they are far from thermal equilibrium, and hence well beyond the regime where such a monotonic relationship can be expected to hold. Being held far from thermal equilibrium, their response to an external electromagnetic field, for example, necessarily depends on the state of the organism at the time when it is exposed - i.e. one is dealing with what are known as non-linear systems, for which exposure to a weak microwave field does not necessarily entail a correspondingly weak response, or vice versa, and for which the ‘window’ phenomena referred to are actually to be expected9, 10! (In this connection, it should be remembered that the concept of a dose-response relationship is one inherited from toxicology, and as such, is in general, inappropriate in the present context. For electromagnetic fields are not alien to the alive organism, but play a fundamental and integral role in its organisation and control, as already noted.)
This dependence of non-thermal influences on the state of
the alive organism must, in general, be expected to undermine the
reproducibility of their detection, thus accounting for the reported effects
being (in some cases) ‘poorly established’. Accordingly, such difficulties should, more
positively, be considered as a biological fact of life – indeed as a ‘hallmark’
of aliveness! It should be noted that
the ‘poorly established’ claim is not universally accepted, as evidenced both
by the Vienna Resolution3 of 1998, signed by 16 researchers of
international standing, and by a recent analysis91 of the ICNIRP document, which claims that it
contains….‘a consistent pattern of bias,
major mistakes and deliberate misrepresentations’.
The least contentious part of the quotation is, of course, the question of the relevance of non-thermal effects (assuming their existence is accepted) to human health - it being, of course, essential to appreciate that the occurrence per se of non-thermal effects does not mean that they necessarily entail adverse health consequences, as already stressed.
In order that the radiation can exert non-thermal influences, it is essential that the organism be alive, for only then are the various oscillatory endogenous electrical activities excited, via which the radiation can access the system: the Dead have no ECG or EEG with which an external electromagnetic field can interfere! Thus, just as a radio or another piece of electronic instrumentation has to be switched on (or energised) before it can respond to or be interfered with by an extraneous incoming signal, so the organism has itself to be energised (i.e. be alive) if it is to be non-thermally sensitive to radiation. Existing Safety Guidelines thus neglect the most discriminating feature of all, namely, the aliveness of the irradiated organism; they address only ‘one side of the coin’ - the thermal side - leaving the exposed person vulnerable to the possibility of adverse health effects provoked by the neglected non-thermal side. The same indictment, of course, applies to any protection device that acts simply to reduce - either by screening or by an employing an ear-piece, for example - the intensity of the microwave radiation emitted by a mobile phone into the head of the user; for the user is still left vulnerable to any adverse health effects that might be provoked by the neglected frequency dimension.
Clearly, non-thermal influences are connected more with the transfer of information from the irradiating field to the alive organism, through the latter’s ability to ‘recognise’ certain frequency characteristics of the radiation92, than with its ability to absorb energy from the field. In order, however, for the organism to be able to discern such weak radiation against the level of its own thermal emission at physiological temperatures, the radiation must have a certain minimum intensity. In the case of microwave radiation, this minimum intensity is, however, far below (of the order of 10-15 Watts/cm2) even that at which non-thermal effects manifest themselves, in consequence of the radiation’s rather well-defined carrier frequency (or relatively high degree of coherence). It should be noted that the magnitude of this minimum power density is close to those that characterise the human thresholds of EEG response93, and also of sight and hearing. Given that the typical power densities in the main beam near ground level some hundreds of metres from a typical base-station, and also in the often neglected ‘side-lobes’, are many orders of magnitude higher than these threshold values, it is clear that the ability of the alive human organism to discern base-station radiation is not at all contingent on a sensitivity that is in any way superior to those that it already possesses (quite undisputedly) in the case of other exogenous fields of physiological relevance.
B-9. Some
recommendations to enhance electromagnetic bio-compatibility
9.1. Policy options for the European Parliament
· That the non-emergency use of mobile phones by children – and particularly per-adolescents – be strongly discouraged, on account of their increased vulnerability to any potential adverse health effects.
·
That the Mobile Phone Industry be required to refrain
from promoting the use of mobile phones amongst children by the use of
advertising tactics exploiting peer pressure and other strategies to which the
young are particularly susceptible, such as the (now discontinued) use of DISNEY
characters fascias on the phones.
·
That the Mobile Phone
Industry be required to make it clear to the consumer that the value of the
specific absorption rate (SAR) -
which in some countries is shortly to be declared on the handset - refers only to the degree to which the
microwave emissions from the antenna can heat biological tissue, and is in no way relevant to non-thermal effects that the emissions from a mobile phone may have
on the user.
·
Concerning commercially
available personal protection devices claiming to protect the user of a mobile
phone against the microwave emissions from the antenna, it be required that:
a) The
efficacy of devices such as shields and ear-pieces be proven on the basis of biological tests, and not marketed
solely on the reduction in SAR value
(as determined by the use of a ‘phantom’ head) that their use might achieve.
b) It be
made clear to the consumer that such devices afford no protection against the
low frequency pulsed magnetic field from the battery of the phone.
·
Concerning commercially
available personal protection devices claiming work by boosting the immunity of
the user against any adverse impacts of exposure (including those from the
battery magnetic field), it be required that:
a) The
efficacy of such devices be established by biological testing.
b) Such
devices not be rejected (as has occurred in certain consumer surveys that have
been published) solely on the grounds that their use does not achieve any
reduction in SAR, as measured using a
‘phantom’ head; for this is not what they are designed to do. Accordingly, the SAR is here a fundamentally
inappropriate metric against which to assess their efficacy.
[It should, however, be appreciated that
in the case of real human exposure –
as opposed to that involving a ‘phantom’ head – such devices could conceivably
achieve a reduction in SAR if they
somehow increase the efficiency of the body’s thermoregulatory mechanism; in
this way, anecdotal reports of a diminution in heating sensation when a phone
is equipped with one particular such device might be rationalised.]
9.2 Policy options for the European Commission
· Future research sponsored by the EC, should incorporate the following recommendations:
a) That the living systems under investigation be exposed to the emissions of an actual mobile phone, as opposed to those of a ‘surrogate’, since the emissions from the former can be expected to have a quite different biological impact, in consequence of certain pulse frequency differences.
b) That in assessing the significance to humans of results obtained using animals, particular attention be given to differences in exposure conditions, such as whether exposure is size-resonant or non-resonant, whether it is to the near or far field of the antenna, and whether whole-body or of more localised exposure occurs.
c) That systematic investigation be made of the influence of different kinds of pulsing (of real phones) on the human EEG, and ideally on the MEG, and of whether any observed changes in power spectra are correlated with changes in the level of deterministic chaos.
d) That use be made of novel, non-invasive technologies, such as biophoton emission, to investigate the influence of mobile phone radiation on living systems.
e) That in assessing the noxiousness of mobile phone radiation more attention be paid to lessons that have been learnt from exposure to other kinds of related radio frequency fields, such as those from the Skrunda, military and police radars.
f) That, in the light of reports of cattle being quite seriously adversely affected at farms where there is a base-station, a veterinary monitoring service be established to collect and analyse such reports, and raise awareness amongst farmers of this potential hazard to their livestock.
· Attempts should be made – perhaps under the aegis of national regulatory bodies - to increase awareness of the fundamentally electromagnetic nature of the alive organism, and of its associated hypersensitivity to coherent, ultraweak electromagnetic signals of technological origin.
[Until this is achieved, the necessity of extending
existing thermally based safety guidelines, by incorporating therein the
dimension of electromagnetic biocompatibility, is unlikely to be accepted, and
the public will remain vulnerable to any adverse health effects provoked by
non-thermal electromagnetic influences on the alive human organism.]
9.3 Technological
options at the operational level
Whilst the question of precisely how adverse health effects can be provoked by non-thermal influences of the pulsed microwave radiation currently employed in GSM telecommunication, as well as those from ELF fields associated with other technologies, is far from resolved, the circumstantial evidence consistent with such influences suggests at least two ways in which biocompatibility with this technology could be enhanced by interventions involving the fields alone:
· In the case of exposure to GSM radiation, reduce intensities to the level below which no adverse effects have been empirically found in exposed populations, bearing in mind that there are indications of non-thermal thresholds for biological effects of the order of microwatt/cm2. Power densities a few tenths of this value are common at distances of 150-200m from a typical 15m high Base-station mast and within the range of the more localised side-lobes in the immediate vicinity of a mast - adverse effects being reported at both locations. Incorporating a further safety factor of 10 indicates that, at locations where there is any long-term exposure, power densities should not exceed 10 nanoW/cm2.
[To appeal to the (alleged) absence of health
problems associated with the higher power density electromagnetic fields
associated with radio/TV transmissions in an attempt to justify the retention
of the present level of emission from GSM
Base-stations is untenable on at least two accounts: (i) the nature of the emissions are quite different, with respect to
carrier frequencies, modes of transmission (pulsed/analogue), and beam
morphology, (ii) there are94-96 health problems
connected with some such
transmitters, contrary to what is often claimed!]
· Ensure that there is no ELF frequencies – either of amplitude modulations (including pulsing, as the extreme case) of RF fields, or of other electric /magnetic fields - in the range of human electrical brain-wave activity, or windows of calcium efflux.
[In the case of exposure to GSM radiation, this will
be achieved, to a certain extent, with the advent of the Third Generation of
mobile phones (UMTS) that utilise CDMA in place of TDMA. For although any
sensitivity to the microwave carrier will remain, the pulsing used in CDMA is irregular; accordingly, CDMA
radiation cannot enjoy the same ‘oscillatory similitude’ with the human
brain-wave activity and electrochemical processes as does TDMA. In consequence,
however, of the somewhat higher carrier frequency used, which is closer to
where water strongly absorbs microwaves, thermal
effects could here become more of a problem, particularly in view of the
somewhat higher powers at which they operate!
The introduction of TETRA,
similarly gives rise to an increased
level of (non-thermal) concern, for the reasons already stated in Section B-1.]
B-10. Conclusions
Absorption of microwave radiation causes heating of biological tissue, which if excessive is deleterious to health; this is undisputed, and forms the basis of current Safety Guidelines, both national and international. In the case of exposure to the microwave radiation used in GSM, these Guidelines are generally not violated. Indeed, in the case of the emissions from base-stations, it has been repeatedly confirmed by field measurements that the emissions are far below - by many orders of magnitude - the limits set by the Guidelines. What is currently disputed, however, is whether, in the case of the alive human organism, this radiation can exert other, more subtle, kinds of non-thermal influences, which might also entail adverse health consequences. The root of the continuing public concern is that if this is, in fact, the case, then the existing guidelines afford an inadequate level of protection, in that they leave an exposed person vulnerable to these non-thermal hazards.
As has been explained, the heating ability of microwave radiation depends primarily on its intensity, and it is essentially only this that the Guidelines restrict. Non-thermal effects, on the other hand, depend primarily on the existence of an ‘oscillatory similitude’ between the frequencies of the radiation and those of certain endogenous biological electrical activities that the organism supports when alive, which effectively opens it to informational aspects of the radiation; it is this dimension of the problem that is not addressed by existing Safety Guidelines.
Whilst the existence of non-thermal influences is readily accepted in the case of active electronic instrumentation exposed to GSM radiation, the same does not currently prevail in the case of the alive human organism, which is generally considered immune to any effect other than heating, despite the fact that, in the case of mobile phone use, the brain (the most sensitive organ of the body) is, for the first time in its evolutionary history, being exposed at short range to a source of both pulsed microwaves (from near-field of the antenna) and more highly penetrating ELF magnetic fields (from the battery). This conviction continues to persist - particularly in Regulatory Circles - despite the fact that the possibility of non-thermal influences on living systems of the kind of radiation used in mobile telephony is a rather general prediction of modern, non-linear biophysics, and one that is supported by 30 years of evidence, both of non-thermal effects per se, and of associated adverse health reactions, in particular – not only from exposure to GSM radiation, but also to that from other kinds of installations that emit microwave and RF radiation of an intensity at locations of human and animal exposure that is comparable to that realised several hundreds of metres from a base-station.
Two principal reasons for this state of affairs have been identified: 1) the negative outcome of some attempts to independently replicate certain non-thermal effects, even in vitro, the acceptance of which is not helped by their often counterintuitive nature (but only from a linear perspective), and 2) uncertainty as to whether such effects (assuming they are real) necessarily entail adverse health reactions. Both these problems have been addressed, and attention drawn (i) to the fact that difficulties in corroboration are actually to be expected as a hall-mark of the ‘alive’, and thus should, more positively, be accepted as a ‘biological fact of life’, and (ii) to the existence of a certain empirical consistency between the contentious non-thermal effects and the types of adverse health effects (mainly neurological) reported by some people when exposed to GSM radiation, as well as that (the indication of an increased incidence of brain cancer amongst mobile phone users) found epidemiological – a consistency that further enhances the credibility of the non–thermal effects, and one that will hopefully motivate further research (from the necessary non-linear standpoint, of course) towards establishing their causal connections with presenting pathologies.
In conclusion, and in accord with philosophy espoused by the World Health Organisation, it can hardly be disputed that to enjoy an acceptable quality of life requires more than simply an absence of terminal disease. In this respect, even adverse health effects of a non-life threatening kind that might be provoked by exposure to GSM radiation must be considered unacceptable, in that they undoubtedly have a debilitating effect that undoubtedly undermines the general well-being of those affected, and which in the case of certain pre-adolescent children could well undermine their scholastic and neurological development.
