MAGNETIC FIELDS BASICS
Cell Phone Research
 |
EMFs,
especially RF EMFs, contribute energy to and cause current in
the body, including the brain and head. RF EMFs are
considered microwave fields. The strength of the microwaves
determines whether it will "cook" tissue. The
most significant measure, in terms of biological effects RF EMFs,
is the specific energy absorption rate (SAR) in tissue, an
estimated quantity, averaged in time and space and expressed in
watts per kilogram (W/kg). The artificial power emitted by
a mobile telephone into the brain is a factor (coefficient) of
10 billion times (10,000,000,000) greater than the currents in
neurons. |
To protect the brain against "chromosome damage" this
coefficient should be 10,000. The brain is also impacted by the
radiation from the sun. This NATURAL radiation has a
coefficient of about "one million" (1,000,000).
It is not surprising that, with exposures millions of times
higher than natural brain currents or the sun, there is
increased brain cell damage and an increased risk of brain tumor
in a signal strength (dose) response manner from extended
use. Whether damage is actually produced needs to be
better studied.
Frequencies
The basic repetition frequency is 217 Hz for GSM and DCS 1800
systems and 100 Hz for DECT; however, the spectrum also contains
a number of higher harmonics due to the narrow pulse. There are
also frequencies in the kilohertz (kHz) range. Owing to
the complexity of these communications systems, there are also 2
and 8 Hz components in the signal, apart from multiples of 100
and 217 Hz. These are in the brain frequency range
(considered ELFs).
Health effects of cell phone signals
 What are the safety standards for
cell phone emissions?
Safety standards for cell phones vary from country to country.
In Europe it is 2 watts per kilogram of brain tissue. The
scientific basis for the standards is that they should make sure
that brain tissue is not "significantly" heated by the
radiation, since heating is believed by some scientists to be
the only potential health hazard associated with cell phone
emissions.
If there are safety standards,
what is the problem?
The problem is that a substantial, growing body of scientific
evidence has demonstrated that there are significant,
potentially adverse biological effects associated with EMFs from
cell phones, which are much lower in energy than the safety
standards. Therefore, many scientists believe that the current
safety standards are inadequate.
There is a robust and ongoing
controversy over many aspects of RF health effects. While no one
disagrees that serious health hazards occur when living cells in
the body are heated, as happens with high intensity RF exposure
(just like in a microwave oven), scientists are currently still
investigating the health hazards of low intensity exposure. Low
intensity exposure is exposure which does not raise the
temperature of the living cells in the body. Cellular antenna
radiation produces a weak level of RF that does not cause
heating, a "thermal effect." Safety standards are
based on induction of thermal effects. There is a large body of
internationally accepted scientific evidence which points to the
existence of nonthermal effects of microwave radiation. The
issue at the present time is not whether such evidence exists,
but rather what weight to give it.
Internationally acknowledged experts in the field of RF research
have shown that RF of the type used in digital cellular antennas
and phones can have critical effects on cell cultures, animals,
and people in laboratories and have also found epidemiological
evidence (studies of communities, not in the laboratory) of
serious health effects at "non-thermal levels," where
the intensity of the radiation was too low to cause heating.
They have found:
 |
increased cell growth of
brain cancer cells
|
|
a doubling of the rate of
lymphoma in mice
|
|
changes in tumor growth in
rats " an increased number of tumors in rats
|
|
increased breaks in double
and single stranded dna, our genetic material
|
|
2 to 4 times as many cancers
in Polish soldiers exposed to RF
|
|
more childhood leukemia in
children exposed to RF
|
|
changes in sleep patterns and
REM type sleep
|
|
headaches caused by RF
exposure
|
|
neurologic changes including
- changes in the blood-brain-barrier
- changes in cellular morphology (including cell
death)
- changes in neural electrophysiology (EEG)
- changes in neurotransmitters (which affect
motivation and pain
perception)
- metabolic changes (of calcium ions, for instance)
- cytogenetic effects (which can affect cancer, Alzheimer's,
neurodegenerative diseases)
|
|
decreased memory, attention,
and slower reaction time in school children
|
|
retarded learning in rats
indicating a deficit in spatial "working memory"
|
|
increased blood pressure in
healthy men
|
|
damage to eye cells when
combined with commonly used glaucoma
medications |

Energy levels
of selected phones
The Table below shows the
estimated energy delivered to the body by the model of the cell
phone and whether it's digital and/or analog. The range of
energy readings in Watts/kg for digital phones is 0.24-1.49 and
for analog phones is 0.40-1.56. The average is 0.96 and 1.25,
respectively. It is assumed that the higher the energy reading,
the greater the risk to the person's head, directly from the
phone and/or mast.

Protection or
shielding
I doubt that most people will
give up their cell phones. The question then becomes, how one
can protect him- or herself and still use a phone. Prevention is
better than protection (also called mitigation). Protection is
probably especially important in youngsters, whose brains are
possibly more strongly affected. The clearest prevention
solution is to use a hands-free attachment as much as possible,
especially for extended calls or frequent use. Hands-free
speakers also produce a small EMF signal, but much, much less
than the phone. Typical hands-free speakers are very much weaker
than larger stereo head phones … and much less than a
telephone speaker or sitting close to a TV or monitor.
 Other options are to use
shielding equipment. Not all shielding is effective. We will
review shielding and offer recommendations for those devices or
applications that have been adequately studied. Shielding is
either of the head itself or the mast of the phone.
This is an example of an effective shield:
