Cellular telephones and
health
ECOLOG-study
by order of the German T-Mobil refers to health risks
The ECOLOG-Institute,
Hannover, has analysed and evaluated the present scientific level of knowledge
on possible health effects of the electromagnetic fields emitted by cellular
telephones and their base stations under the criterion of precautionary health
protection. The results and recommendations of the comprehensive study carried
out by order of the German T-Mobil, in which physicists, medical scientists,
and biologists took part, are present now.
Results:
There are a number of
scientific findings from investigations on sub-populations with an elevated
exposition to high frequency electromagnetic fields and from animal
experiments that have to be taken seriously. These findings point on a
cancer-promoting effect of high frequency electromagnetic fields used by
cellular telephone technology. Experiments on cell cultures yielded clear
evidence for geno-toxic effects of these fields, like DNA breaks and damage to
chromosomes, so that even a cancer-initiating effect cannot be excluded any
longer. The findings that high frequency electromagnetic fields influence cell
transformation, cell promotion and cell communication also point on a
carcinogenic potential of the fields used for cellular telephony. Moreover
disturbances of other cellular processes, like the synthesis of proteins and
the control of cell functions by enzymes, have been demonstrated.
In numerous experiments
on humans as on animals influences on the central nervous system were proven,
which reach from neuro-chemical effects to modifications of the brain
potentials and impairments of certain brain functions. The latter effects for
instance have been demonstrated by animal experiments and e.g. showed up as
deficits in the ability to learn simple tasks when exposed to the fields. From
experiments with volunteers, who were exposed to the fields of mobile
telephones, there is clear evidence for influences on certain cognitive
functions. Possible risks for the brain also arise from an increased
permeability of the blood-brain barrier to potentially harmful substances,
observed in several experiments on animals exposed to mobile telephone fields.
The scientist at the ECOLOG-Institute also found some evidence for disturbances of the hormone and
the immune system. High frequency electromagnetic fields cause stress
reactions, showing up in an increased production of stress hormones in
experimental animals and they lead to a reduction of the concentration of the
hormone melatonin in the blood of exposed animals. The latter finding is
important, because melatonin has a central control function for the hormone
system and the diurnal biological rhythms and it is able to retard the
development of certain tumours.
Comment:
Dr. Peter Neitzke, co-ordinator
of the working group at ECOLOG-institute:
"Our work focused on
effects of the high frequency electromagnetic fields of cellular telephones on
humans and animals, which occur at so small intensities that a thermal effect
can be excluded. We critically checked the corresponding studies with respect
to the applied methodology, completeness of the documentation, and strength of
evidence of the results. During these checks it turned out that about 80 per
cent of the papers published in scientific journals do not contribute anything
to the evaluation of possible health risks due to the electromagnetic fields
emitted by cellular telephones and their base stations. The remainder however,
on which our assessment relies, is made so good and is in itself so consistent
that we must take the findings referring to health risks seriously. In order
to improve the protection of the public against the possibly harmful effects
of the electromagnetic fields from cellular telephones and their base
stations, we need much lower precautionary standards in Germany, as they
already exist in some European neighbouring countries. The experiences from
these countries show that precautionary health protection and the use of the
cellular telephone technology are compatible."
Recommendations:
The German safety
standards for the frequencies used by cellular telephone systems range from 2
to 9 W/m2. These values only limit the warming up of the body due to the
thermal effect of high frequency electromagnetic fields to a tolerable degree.
From the point of view of the authors they are not suitable to exclude health
risks for the public as pointed out in their study. They are therefore not
compatible with the principles of precautionary health protection. The
ECOLOG-institute
recommends not to exceed a precautionary standard of 0,01 W/m2 when siting
cellular telephone base stations in the proximity of dwellings, schools,
kindergartens, hospitals, and similarly sensitive uses. ECOLOG recommends also
that the cellular telephone operators keep this standard on their own
immediately and that they not wait for the ratification of the revised version
of the federal immission control law.
Keeping the standard
recommended for the neighbourhood of cellular telephone base stations is not
possible with the direct use of mobile telephones at the present state of the
art, but in the opinion of the scientists at the ECOLOG-institute a reduction
to max. 0.5 W/m2 should be urgently aimed at. They see a special problem in
the use of mobile telephones by children and young people, since their
organism is still developing and thus particularly sensitive. On the other
hand meanwhile many adolescents are regular users of mobile telephones. ECOLOG
recommends to stop at least advertising in this sub-population. Additionally
special efforts should be undertaken in order to reduce the electromagnetic
exposition when telephoning by technical modifications at the telephones. Also
by the use of head sets or guarding pockets the intensity reaching the head
can be reduced.

Dear Roy,
For genotoxic signals the
"safe" level is zero mean exposure because the cells of the brain and body are
damaged cell-by-cell. Any mistakes in DNA repairs can lead to cell death or
cancer. This is why Dr Jerry Phillips found that cellphone radiation caused
highly significant (p<0.0001) DNA repair (initiated by DNA damage) and DNA
damage at an SAR of 0.0024 W/kg and Dr David De Pomerai at Nottingham showed
that microwaves at 0.001 W/kg highly significantly (p<0.001) induced
production of heat shock proteins, i.e. a non-thermal toxic shock response.
The actual expose levels at which these genetic effects are shown are about
0.5 to 1.2 microWatt/sq cm. These are not safe levels, they are just
experimental levels that show that at extremely low experimental levels
genotoxic response occur - cell-by-cell. There is no safe threshold.
An acute human effect is
sleep disturbance, a consequence of RF induced melatonin reduction. Sleeping
with a cellphone on next to your bed, exposing your head to 50 microwatts/sq
cm, causes sleep disturbance and altered EEG patterns. The University of Berne
team carrying out the Schwarzenburg Study, found a causal relationship between
shortwave radiation exposure and sleep disturbance (with measured melatonin
reduction). The causal relationship was concluded because of dose-response
relationships in two surveys, and experimentation involving turning the tower
off for three days and altering the beam directions at other times. With an
established biological mechanism and a multivariate analysis of confounders
that we able to be eliminated, they concluded that there was a causal
relationship. When the tower was turned off for three days the sleep
disturbance improved in all study groups, including the reference Group C,
that was exposed to measured field strengths (24 hr average) of 0.1 mA/m. This
converts to 0.4 nW/cm sq. (n=nano). This value of 0.4 nW/cm sq is also not a
safe level because it was causing significant sleep disturbance and a
reasonable proportion of the population.
Hence RF/MW is genotoxic
(from over 20 studies) and acutely neurologically active at extremely low
exposure levels. Allowing for a small safety factor of 4, the risk reduction
target could be 0.1 nW/cm sq.
For ELF fields Sam Milham's
work is crucial. He shows that normal residential fields less than 1 mG have
massively increased the incidence of early childhood Acute Lympoblastic
Leukaemia (ALL). This is just an indicator cancer. If these fields produce ALL
then they produce all other cancers that have risen in parallel with childhood
ALL over the first half of the 20th century. Our New Zealand Ministry for the
Environment recommend for air pollution that we set exposure guidelines for
fine particulates at an achievable level and then regulate to keep below the
guideline with being below 33 % of the guideline is good and 10% of the
guideline is excellent. Hence I recommend, using Sam's work and reviewing the
more than 10 other studies showing dose-response increases in childhood cancer
as a function of residential magnetic field exposures, and the recent
occupational studies from David Savitz's group on suicide, cardiac death and
brain tumor, to set the guideline limit of the maximum allowable exposure of 1
mG and aim for living in an excellent field of less than 0.1 mG.
If we adopted these
guidelines and strove to achieve them over the next 10 years, we would see a
massive reduction in many health effects that are currently attributed to
"unknown causes". Because of the frequency response of RF/MW fields as shown
by the logarithmic reduction in dielectric constant with increasing carrier
frequency, all the electrical residential and occupational effects found with
ELF dominated exposures, will be produced at far higher rates by RF/MW
exposures. The "wireless world" is a humanly created world that is a very
dangerous place because people, animals and plants evolved over millions of
years in a natural world with extremely low intensity ELF (Schumann
Resonances) and RF/MW from space.
While we know that
tgechnology has improved our lives in many ways, we also know that there are
many ways to use it more responsibly, creating much lower exposures while
still maintaining services. All of our telephone, fax, internet, radio and TV
signals can be carried in fibre optic cables in urban areas, giving massive
reductions in enviromental fields. Energy efficiency and passive solar designs
can signficantly reduce the electrical requirements and fossil fuel
requirements to heat homes in many parts of the world. A sound smart approach
to technology can reduce ELF/RF/MW exposures, reduce air pollution and make a
much more safer, cleaner and sustainable world.
Most of us have a vision of
a clean, green world with a safe environment for our children. We have to
recognise that we have inadvertantly created a dangerous world and reverse the
trend so that our visions and dreams can come true.
Lets all light a candle,
and use our scientific and technical knowledge, and the global communication
available through this technology, to achieve our vision.

Here is a short background
on Dr. Cherry available on the Lincoln University web site:
Dr. Cherry joined the staff
of Lincoln in 1974, having completed a PhD in physics at the University of
Canterbury, 2 years at McGill University in Montreal and one year at Auckland
University.
Dr. Cherry established
meteorology and climatology as a teaching and research discipline at Lincoln
and built a national and international profile for Lincoln's role in weather
and climate research, particularly in wind and solar energy, climate change
and seasonal forecasting, human biometeorology and the effects of natural and
artificial electromagnetic radiation on people's health. Hence Dr. Cherry's
teaching and research links the concern for global health to personal health.
