2.5 times risk of brain tumours
from phone radiation in humans?
Early Alzheimers disease from destroyed brain cells?
Each month we see more reports about mobile phone radiation effects -
but what does it actually mean for you and me? Is there really a health
risk? Here is a common-sense personal view from a physician and parent
of four children who is also a major user of wireless devices of all kinds.
New reports continue to be published suggesting that there might be health
risks from mobile phones electromagnetic radiation. There can be no doubt
any longer that mobile phone radiation affects living cells. For example
research shows that nematode worms exposed to mobile phone radiation produce
more eggs, release stress hormones and grow larger. But what is the effect
of mobile phone radiation on people? Could we see a mass court action
in twenty years time against telecom companies by people claiming compensation
for health damage caused by radiation? It's a possibility, even though
at present the clear evidence suggests that if there is any effect on
human health at all, it is a very, very low risk for the individual user.
However some studies have caused concern in the media. For example, in
March 2003 a study in the International Journal of Oncology suggested
that mobile phone users had a 30% increased risk of brain tumours - mainly
acoustic neuromas - which occurred close to the ear used for mobile phone
listening. Previous studies had shown that growth of leukaemia cells could
be increased dramatically after exposure to mobile phone radiation./p>
What makes these studies difficult to evaluate is that other research
has not shown the same findings. And the effects may be very different
depending on the type of electromagnetic radiation. GSM and GPRS (2.5G)
phones use what is known as pulsed radiation. The levels rise and fall
very rapidly. 3G phones on the other hand use continuous levels. Some
research suggests that pulsed radiation may have a greater effect on cells
than constant exposure, which is important because different studies have
used different types of radiation - perhaps an explanation for some of
the more confusing results.
Short exposure to mobile phone radiation kills
brain cells in rats
Short exposure to mobile phone radiation - two hours - has been reported
in 2003 to destroy cells in parts of the brain important for memory, movement
and learning, and could possibly conceivably premature onset of illnesses
such as Alzheimers - although we have no evidence of a similar effect
in humans. Lund University Hospital Professor Leif Salford says mobile
radiation allows harmful proteins and toxins through the brain barrier
in rats. He also has found significant degree of damage to brain neurons
in adolescent rats.
He said: "If this effect was to transfer to young mobile users,
the effects could be terrifying. We can see reduced brain reserve capacity,
meaning those who might normally have got Alzheimer's or dementia in old
age could get it much earlier." He used rats aged 12-26 weeks because
their brain cells were still developing in a similar way to teenagers
and younger children. They were exposed for just 120 minutes to radiation
equivalent to typical intensive mobile phone use. Sections of rat brains
were examined 50 days after exposure. Animals exposed to medium and high
level radiation had many dead neurons in their brains - totally different
from rats which were not exposed to radiation. (published Feb 2003).
The trouble is that similar studies cannot be carried out in humans because
mobile phone radiation exposure would have to be followed by brain biopsy
which can cause epilepsy later, permanent brain damage, stroke or even
death. We can only get the answer in humans by doing studies on brain
tissue of teenagers killed in accidents, and comparing brain tissue of
heavy, medium, light and non-users of mobile phones. In addition, we have
yet to see other centres replicate his work.
Dr Kjell Hansson Mild in Sweden studied radiation risk in 11,000 mobile
telephone users. Symptoms such as fatigue, headaches, burning sensations
on the skin were more common among those who made longer mobile phone
calls. At the same time there are a growing number of unconfirmed reports
of individuals whose health has been affected after chronic, frequent
use of mobile phones, presumably from radiation effects on cells. See
below for SAR data on mobile phone radiation levels. Once again, for every
study with a positive finding of effect on cells, there is another that
has found nothing.
As I say, from a physician's point of view this is all rather difficult
to interpret. The truth is that no one knows for sure, but it looks as
though the health risks for an individual person with normal patterns
of use are extremely low, almost non-existent. I still use a mobile phone,
as do our teenage children, and my home has a wireless network as well
as hands-free local handsets for landlines. The only steps we have taken
are to mount the wireless LAN connection a few feet from where anyone
sits, and to encourage our younger children not to spend their entire
lives chatting away on mobiles - there are other reasons for that too
such as homework and of course cost.
Latest mobile phone radiation news - press here
NOW!
As long ago as June 1998 the Lancet reported that radiation from mobiles
caused an increase of blood pressure. Dr Braune and colleagues in Freiburg,
Germany, attached mobiles to the right side of the heads of ten volunteers.
The phones were switched on and off by remote control without the volunteers
knowing - so that any radiation effect could be separated from the psychological
effect of holding a mobile phone. Their blood pressure rose each time
by between 5-10mm Hg, probably from an electromagnetic radiation induced
constrictive effect on blood vessels from the mobile phones.
This level of increase would be more than enough to trigger a stroke
or heart attack in someone at severe risk, but is harmless in the vast
majority of people. This was the first firm evidence that mobile phone
radiation could directly alter cell function in the human body. But what
about longer term radiation effects of using mobile phones? Could mobile
phone exposure trigger cancer? Birth defects? What about the health risks
not just from mobile phones but the transmitter masts?
This work on human subjects follows other ealier mobile phone studies
in animals suggesting that electromagnetic radiation from mobiles may
cause brain tumours, cancer, anxiety, memory loss and serious birth defects.
But different studies have contradicted many of these findings. As in
so much of cutting edge science, there are real uncertainties about mobile
phone radiation. Remember it has taken 30 years to work out the side-effects
of oral contraceptives and even that is still debated. Here are some of
the more negative reports.
An Australian study found that mice exposed to pulsed digital mobile
phone radiation over 18 months had twice the risk of developing cancers.
An American study found that learning and short term memory were impaired
after 45 minutes exposure to electromagnetic radiation from mobile phones
in rats. And other studies of electromagnetic radiation on pregnant mice
suggest that high exposure to mobile phones can affect intra-uterine development,
confirmed recently in chicks (double birth defects, see below). The effects
of mobile phone radiation in human embryo development are unknown.
Meanwhile, The European Union is drawing up
guidelines for electromagnetic radiation exposure of all types.
Mobile phones vary on radiation dosage: Following figures are for European
mobile phones in SARS (watts of radiation from mobile phones per kg of
brain), antenna extended / retracted. Safety is 10 watts/kg. Lowest radiation
levels from phones with hidden antennae or ones extended away from head.
Below that are SAR levels for US mobile phones. Note that there are different
figures for SAR levels around for the same mobile phones, I suspect because
some are official company data, and others independent lab measurements
and that there may be other variables according to the exact conditions.
For example the first table below shows big SAR phone radiation differences
depending on the position of the aerial.

Mobile Phones & Your Health
Results of recent research in Australia, Europe and the USA,
together with reports by the European Commission that mobile phones
may not be as safe as first thought, has led to major concerns being
expressed about the health effects associated with their usage.
In what ways can mobile phones affect your health?
The most frequently reported symptoms made by users to both their doctors
and also to phone manufacturers, is the occurrence of unexplained headaches,
ear and eye sight problems, feelings of nausea or dizziness, a tingling
sensation on the skin and a numbness or redness to the face and neck. A
leading Swedish scientist, Professor Mild who is on the European Commission
panel of experts investigating mobile phones, confirms frequent reports
of such conditions, as does Dr Bruce Hocking, former Chief Medical Officer
for Telstra. On May 7 1997, Dr Hocking presented the results of a study
of neurological symptoms in mobile phone users. When asked about this study
on the "7.30 Report" of May 7, Dr Hocking replied: "Yes,
these are studies I've been doing on people who use mobile phones and who
develop symptoms when using the phones. This arose from some other observations
I've made when working for Telstra that staff and customers were developing
symptoms. I've now followed up with a detailed survey of over 40 people
around Australia who have developed symptoms. They complained mainly that
they developed a burning dull feeling on the side of the head where they
have been using their mobile phone. It tends to come on several minutes
after they made their call and may last for hours. Associated with this
they may get feelings of nausea, disturbances in their vision and at times
other neurological symptoms." When asked by the "7.30 Report"
presenter: "With all due respect to these people, how do you know that
they are not just psychosomatic symptoms?" Dr Hocking replied: "Yes,
this question has been asked by quite a few people. 1.
First of all there is the consistency of symptoms. People from all over
Australia with no connections, produce a rather similar story.
2. Secondly, there are now reports coming from overseas,
Scandinavia, Great Britain and America of people getting similar kinds
of symptoms.
3.Thirdly, there is a statement from the Department of Communications
recently out about the development of "hot spots" in the brain.
This means a concentration of energy which would give a possible explanation
for these symptoms.
4. Fourthly, and most interestingly, these symptoms were
in fact observed over 30 years ago in a laboratory set up." The UK's
National Radiological Protection Board (NRPB) confirms significant absorption
of microwave energy in the eyes and their sockets, brain, nose, tongue
and surrounding muscles. A senior adviser to the NRPB has been reported
in the British press as saying: "It is not unreasonable to suggest
that this might cause some damage." The worry is that these overt
symptoms may be the precursors to more serious problems and not all users
are getting these early warning signals.
Is the problem more serious?
Research funded by the New York Heart Research Foundation as early as
1992, showed that microwave radiation from a relatively low powered analogue
mobile phone, caused chemical changes in the brain similar to those present
in cancerous and precancerous situations, which were still measurable
more than 7 days after just one 3 minute phone call. Research published
in 1996 by doctors Lai and Singh of Washington State University, Seattle,
demonstrates that exposure to extremely low level microwave radiation
causes single and double strand breakages in DNA brain cells of rats.
An accumulation of DNA breakages is known to be associated with the slow
onset of diseases such as cancers, Alzheimer's, Parkinson's and Huntington's.
The frequencies used in their experiments are known to be less penetrative
than those emitted by mobile phones and the power levels were substantially
lower. Adding to growing evidence that electromagnetic fields may be linked
to Alzheimer's disease, a 1996 US study by Dr Eugene Sobel, published
in the journal Neurology, found that people who are exposed to high electromagnetic
field (EMF) levels on the job have, on average, three to five times the
normal risk of contracting the disease. These results follow on the heels
of a September report from the US Centre for Diseases Control and Prevention
indicating that a broad variety of neurodegenerative diseases, including
Alzheimers, are more common among workers exposed to EMF on the job. About
50 studies have now reported statistically significant increased risks
for several types of cancer in occupational groups with elevated exposure
to electromagetic radiation. In microwave and radar personnel they have
noted sharp increases in lymphomas, melanomas, leukemias, and brain tumours,
high blood pressure, headaches, memory loss and brain damage. Immune system
abnormalities were also noted: first an over stimulation, then later immune
suppression after continued exposure to low levels of microwave radiation.
A recent Australian study, funded by Telstra, conducted at the Royal Adelaide
Hospital by Dr Michael Repacholi, Professor Tony Basten, Dr Alan Harris
and statistician Val Gebski, revealed a highly significant doubling of
cancer rates in a group of mice exposed to electromagnetic radiation equivalent
to spending two half-hour periods each day on a digital mobile phone.
How is microwave radiation absorbed by the body? EMR (electromagnetic
radiation) is a form of energy which is emitted by amongst other things,
electrical appliances. EMR in the form of microwave radiation is given
off by a mobile phone through the keypad, screen, ear-piece and aerial
when the phone is switched on, and particularly when in conversation.
Unlike an ordinary phone, a mobile phone's power unit and transmitter
is located in the handset. Research by the UK's National Radiological
Protection Board has shown that microwaves penetrate through the skull
and into the brain. In addition, the ear, the eye and its socket, the
nose and other surrounding tissue, also show significant absorption. Radiation
levels are always at their strongest closest to the EMR source. With a
mobile phone in operation, the concern is that the user could hardly get
any closer to the handset. "You would not put your head into a microwave
oven, but people are quite happy to hold a mobile phone next to their
head" Senior Physician, Danish Board of Health European Health and
Safety Journal 1995
But don't mobile phones comply with current
safety standards?
Manufacturers claim that their phones are safe because they comply with
current safety standards. However the validity of these standards are
now being challenged both within the scientific community and, increasingly,
in the courts. The current safety standards are being questioned because:
1.Firstly, the standards are based solely on heating (thermal) effects
of human tissue. This suggests that unless you are being cooked, you need
not worry. However, the European Commission Public Health Directorate
confirms that microwave radiation from cellular phones induces heating
in tissues and organs and that temperature rises of only 1 degree Celsius
can produce a variety of health effects which become more severe with
higher temperature rises. (Tests carried out in Australian cellular industry
laboratories have shown temperature increases of over 4 degrees Celsius)
When asked in 1995 if it was still advisable to base standards solely
on thermal effects, the chairman of the USA's National Council for Radiation
Protection and Measurement Committee replied: "...the laboratory
evidence for non-thermal effects of both ELF and RF/microwave fields now
constitutes a major body of scientific literature in peer reviewed journals.
It is my personal view that to continue to ignore this work in the course
of standards setting is irresponsible to the point of being a scandal."
Of note, two military research bases in the USA reduced their permitted
levels of radio frequency exposure significantly (from 100W/m2 down to
1W/m2). This is because they acknowledged that there is now an overwhelming
body of published evidence of the positive existence of non-thermal biological
effects of high-frequency radiation.
2.Secondly, because the current safety standards are set on the assumption
that microwaves are distributed evenly throughout the head. However, evidence
is emerging that "hot spots" may be formed within the brain
which could cause more damage than previously assumed. It has been shown
that digital mobile phones can deliver well over the safety levels into
head tissue in their output pulses, but they are said to comply because
over each second the average power is only one-eighth of the pulse power.
To give a clearer analogy, this is like the health department saying that
it is safe to drink 14 standard drinks at one time because this averages
out to only 2 standard drinks per day over a week. Unlike the earlier
analogue mobile phones, the newer digital ones emit a series of radio
frequency pulses. This has been shown to be more biologically active than
a continuous radiation of the same frequency and power level. These pulses
are picked up and detected by the cells inside the user's and other nearby
people's heads. This means that the brain cells are being "hit"
by these radiation pulses, and this is what is now raising concern amongst
researchers. To use another analogy, while a constant light does not harm
anyone, if it is switched on and off like a strobe, serious neurological
symptoms can be triggered. It is also important to consider exactly who
is setting these safety standards. In Australia, the Standards Committee
consists of 12 representatives, of which nine are users or sellers of
the technology. Thus it could be said that there is a conflict of interest
for those who set the standards. When Dr Bruce Hocking, former Medical
Officer for Telecom, was asked on the "7.30 Report" about the
governments policy management on this issue, he replied: "First of
all, I think it's a mistake to put the major responsibility for this issue
into the Department of Communication and the Arts. They have a potential
conflict of interest. They are a major revenue raiser for the government,
from license fees as well as the proposed sales of Telstra and of future
frequencies for mobile phones. They would not be wanting to create too
much concern that some of these products may be unhealthy to the public,
as that would impact on their revenues, and yet they are responsible for
the dissemination of information regarding this. I think it would be fairer
to the government and the public alike if the responsibility for all health
public issues were moved firmly into the Department of Health Branch area
and administered out of there." It appears that a "conflict
of interest" situation also exists in the USA. The Wireless Technology
Research (WTR) group, which is funded by the mobile phone industry has
become embroiled in a number of scandals. The WTR was promoted to the
public and to the US government as being an "independent" and
"arms-length" body controlling $25 million in research funding.
Recent leaked documents show that it has been under the direct control
of the industry association, and it has long operated as a PR front. In
the last four years it has spent $17 million "without wetting a test-tube"
according to Microwave News editor, Louis Slessin. The WTR scientists
recently went on strike for nearly a year, refusing to perform their contracted
research until adequately covered for indemnity against law suits, by
the mobile phone industry association. The US scientists' sensitivity
to this issue follows the filing of 38 cases which are now before the
courts over past tobacco-safety studies. Both the tobacco company lawyers
and the scientists they funded have been charged as co-conspiritors with
the Tobacco Institute and the cigarette companies in suppressing evidence
and manipulating research results. If manufacturers genuinely believe
that their mobile phones are completely safe then why: Do many of them
suggest in their handbook that users may wish to reduce their exposure
by spending less time on the phone? Why would three manufacturers have
lodged their own patents to reduce radiation emissions which in the word
of the patent abstracts are to "prevent the health of the user from
being damaged"? Why has one manufacturer just launched a new low
radiation mobile phone? Why are many manufacturers developing antenna
which point away from the head? Why is the mobile phone industry spending
millions of dollars on medical research looking for evidence of a problem
which they categorically assure people doesn't exist and why have they
refused funding to independent scientists whose research looks as if it
might reveal damning conclusions? The answer to many of these questions
probably lies in current litigation claims being filed against mobile
phone manufacturers, marketers and service providers. While there may
be no "conclusive scientific data" to prove that mobile phones
are a health risk, it seems there are increasing numbers of people challenging
in the courts the current ideology that mobile phones are safe. Kane v.
Motorola In this case, Robert Kane, an engineer for Motorola, alleges
that he developed a brain tumour from exposure to radio frequency EMF
which resulted from his testing of an experimental mobile phone antenna.
Also named as defendants are Kane's manager, the principal designer of
the antenna, and Motorola's chief research scientist for mobile telephones
and antennas. Rittman v. Motorola In August 1995, attorneys for the estate
of Dean Vincent Rittman and family who survived him filed a lawsuit against
several mobile telephone manufacturers and marketers and two cellular
service providers, alleging that Mr Rittman's fatal brain tumour was caused
by his use of mobile telephones. This case was filed in Tarrant County,
Texas. Listed as defendants are Motorola, Inc; NEC USA, Inc; NEC America,
Inc; General Electric Company; Ericsson, Inc; GTE Corporation; GTE Mobilnet,
Inc; GTE Mobilnet Service Corporation; GTE Mobilnet of Houston, Inc; SBC
Communications, Inc; Southwestern Bell Mobile Systems, Inc; Discount Communications,
Inc; and Parkinson Electrical Company. The complaint contains claims for
negligence, strict liability, breach of express and implied warranty,
civil battery and violations of the Texas Deceptive Trade Practises Act
(DTPA). Also, a leading research laboratory in the UK has formally advised
Motorola's German headquarters that it intends to file an action against
Motorola for failure to comply with certain sections of the Consumer Protection
Act 1987. The impending action alleges that Motorola has failed to affix
warning labels to its mobile phone handsets advising consumers that prolonged
usage may give rise to adverse health risks. The Consumer Protection Act
1987 is derived from a European Directive imposing, a duty on producers
and distributors to ensure that products made available to the public
are safe, or and that warning labels are affixed where there is any doubt.
So what do insurance companies think about all
this litigation?
A giant Swiss Insurance company, Swiss Re, has raised serious concerns
for the insurance industry as to future liability for claims against health
damage caused by electromagnetic emissions including mobile phones Up
to now, the prevailing legal opinion is that industries can only be liable
if science provides conclusive proof that weak electromagnetic fields
impair health. The question on whether or not EMF's are a real hazard
is no longer an issue when it comes to possible future litigation pay
outs for insurance companies. The EMF problem is more dangerous and more
threatening for the insurance industry than has generally been supposed.
Swiss Re's report comes to the conclusion that on the basis of present
knowledge alone, it must be expected that the plaintiffs will win suits
dealing with this issue. There is obviously the risk that new research
findings will demonstrate electromagnetic fields to be more dangerous
than has been assumed. This follows a recent incident by Australia's leading
insurance company, Mercantile Mutual, who objected plans by Vodaphone
to build a transmitting tower on its Sydney office block. In its formal
objection it said: "there is an increasing body of scientific and
medical evidence of the risk to health posed by exposure to emissions
from telecommunication base stations. The risk to health may expose us
as owners of the property to liability for injury to persons who are even
alleged to have been exposed to emissions from the base station".
Of note, according to a recent Telstra report mobile phone handset signals
are between 100 and 46 000 times higher than maximum base station transmitters
!
Is it worth taking the risk?
Mobile phone companies will assure you that their products are safe because:
Claim 1# Mobile phones comply with current safety standards
However, as mentioned previously, the methodology of the safety standards
are being called into question by leading researchers, as is the motivation
of those setting the standards.
Claim 2# There is no evidence of a link between mobile phones
and ill-health. The recent Telstra funded Royal Adelaide Hospital mice
study, which found over a two fold increase in cancer in the mice exposed
to a digital phone frequency, was called into question by its own researchers
who stated: "mice and humans absorb energy from these fields differently,
so we cannot conclude from this single study that humans have an increased
risk of cancer from the use of digital mobile phones." It would seem
to be a rather futile exercise then to conduct research on mice and then
when damning results occur, call the whole study into question because
it was based on mice!!! Essentially, what they are saying is that the
only conclusive research will be when humans exposed to mobile phone radiation
show a two fold increase in cancer. Dr Neil Cherry, a scientist from Lincoln
University, New Zealand states: " Despite the impression that mobile-phone
companies give in their literature, very little work has been done on
the long term implications of mobile-phone use. In fact this type of research
is really only starting to happen now. This means that current mobile
phone users are acting as involuntary, and often unsuspecting, test subjects.
Past research into microwave radiation effects certainly gives rise for
concern. If you are completely healthy, and have a strong immune system,
then mobile-phone use may well not give you long-term health problems.
Some people can smoke twenty cigarettes per day for fifty years and not
develop lung cancer, and yet the dangers of smoking are now generally
accepted. Most of us regularly develop cancerous cells in our bodies.
Normally the deranged cells are destroyed by our immune system. However,
it has been repeatedly shown that a few minutes of exposure to cell-phone
type radiation can transform a five percent active cancer into a ninety-five
percent active cancer. Most of us remember the Thalidomide tragedy - the
result of a product being used widely before adequate long term research
had been carried out. The result has been such a misery for the families
involved, and long drawn out and expensive lawsuits. Another example is
asbestos which has been strictly controlled since 1970, and the most dangerous
types banned. Despite this, deaths from mesothelioma (an asbestos induced
cancer of the pleura/lungs) are rising consistently and the UK death rate
is not expected to peak until about 2020. The time between the first exposure
and death is now accepted as often being between 20 and 50 years. Most
environmental cancers in adults take longer than ten years from initiation
to when they are detected."
Other considered conclusions:
"I am now convinced that EMF's pose a health hazard.
There is a statistical association between magnetic fields and cancer
that goes beyond the shadow of reasonable doubt. I think there is clear
evidence that exposure to EMF's increases the risk for cancer. This is
most clear with leukemia and brain tumours, but in the residential studies,
statistical significance increased for all kinds of cancer. And we're
just beginning to have a whole body of evidence that reproductive cancers
are increased by exposure." Dr David Carpenter, Dean of the State
of New York School of Public Health
" In all my years of looking at chemicals, I have never
seen a set of epidemiological studies that remotely approached the weight
of evidence that we're seeing with ELF (extremely low frequency) electromagnetic
fields. Clearly something is happening here." Martin Halper, Environmental
Protection Agency (US) Director of Analysis and Support
"Based on the data base we have right now, I think
the probability of hazards to human health from exposure to EMF's is high.
It has been pretty well accepted by most scientists now...The issue is
not whether there is biological effects or possible harm, but at what
level and what duration of exposure - that question we have not answered."
Dick Phillips, Director of Experimental Biology Division, Environmental
Protection Agency (US)
"We will proceed on the assumption that there is a
connection between exposure to lower frequency magnetic fields and cancer,
in particular childhood cancer." Swedish National Board of Industrial
and Technical Development.
"...Sweden has concluded that EMF's do lead to higher
rates of cancer...I, frankly was somewhat impressed by the arguments made
by the Swedes." President Bill Clinton
So what can I do to protect myself?
The Australian Consumers Association (ACA), has advised users to minimise
their exposures to the electro-magnetic radiation emitted by mobile phones.
"While there is no scientific proof that phone radiation can be harmful,
neither is there proof that it is safe" said Steve Horracks, from ACA.
"If it turns out that there is a problem with electro-magnetic emissions
at mobile frequency ranges, then using a device that operated so close to
your head is an obvious reason for concern." "It would seem reasonable
to take a few precautions until more is known about the potential risk.
Mobile users should consider their usage patterns and habits to see what
they can do to reduce their exposure. There are a number of practical things
that mobile phone users can do if they are concerned about the potential
health risk." The Australian Consumer's Association suggests:
don't use your mobile phone when a normal phone is handy; always extend
the antenna consider using an after market hands-free kit consider installing
a car kit if you have a digital phone try and use it in open space as much
as possible so that the phone can transmit at a lower power level limit
the number and duration of calls (Choice Magazine, May 9,1997) Similar recommendations
have been made by Dr Peter French, Principle Scientific Officer of the Centre
for Immunology at Sydney's St Vincent's Hospital. "Until there is more
conclusive evidence about possible health risks, we should be cautious about
mobile phones" he said. "If you're experiencing symptoms that
may be mobile-related (such as headaches or blurred vision), see your doctor.
If you want to reduce your exposure to the electromagnetic radiation coming
from your phone, try these practical steps:" Cut down on the number
of calls you make keep the phone calls brief make use of pagers and message
banks, and use an ordinary phone to return calls try using devices that
increase the distance between your head and the phone. A hands free kit
(including one for the car with an outside antenna) is a good idea, as is
a cover that shields you from the radiation carry the phone in your handbag,
not in your pocket and if you have children, you should limit the number
of mobile calls they make.
What if I can't limit the number of calls I make or the length
of my calls, because I use my mobile phone for work?
There are a few products available to reduce the amount of radiation recieved
from mobile phones. As mentioned above, there are the hands free devices
which are readily available from most telecommunication outlets. UPDATE:*
Tests Confirm Hands Free Kits Not So Safe After All.(Click here for more
info) With regard to shielding products, there are a few products available
which substantially reduce the microwave radiation emitted by mobile phones.
