Cell Phone Safety Standards Not Safe Enough
by Taraka Serrano
If you think your
cell phone's low SAR rating will keep you safe from your phone's radio
frequency/microwave radiation, think again. Several studies have shown
that even low-intensity radiation, up to 200,000 lower than existing safety
standards, produces biological effects.
What is SAR, anyway?
Specific Absorption Rate (SAR) is a measure of the amount of radio frequency
energy absorbed by the body when using a mobile phone. The FCC has adopted
limits for safe exposure to radio frequency and requires cell phone manufacturers
to ensure that their phones comply. Any cell phone at or below these SAR
levels (that is, any phone legally sold in the U.S.) is a "safe" phone,
as measured by these standards. The FCC limit for public exposure from
cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg).
(You can request your cell phone's SAR information from the manufacturer
or your carrier.)
When radio frequency
energy impinges upon your body tissue, part of it is absorbed and converted
to heat due to ionic conduction. This heat manifests itself as a temperature
increase inside the tissue. Earlier on the government and the industry
have come to the conclusion that if this heating is below a certain level,
then the radiation level is safe.
from Low Exposure
But several laboratory studies show that nonthermal (non-heating) effects,
including those occurring at levels way below the current SAR standards,
can be dangerous. During the past several years three out of four independent
(non-industry sponsored) research studies worldwide have been showing
these nonthermal effects, which include:
- DNA damage and nonrepair
- breakdown of the blood-brain barrier (allowing chemical toxins and pathogens
to reach the brain)
- lowered immunity
- decreased melatonin levels
- effects on stress proteins (indicating cell damage)
- formation of micronuclei (aberrations in cell nuclei which are often
markers for cancer)
- changes in calcium metabolism affecting communication between cells
- changes in brainwave patterns as seen on EEG's
- plus effects observed on many different systems of the body.
Researchers are cautious
in drawing any conclusions that these effects are directly linked to major
health problems like cancer and neurological conditions. They are, however,
plausible precursors to such conditions, and some evidence suggests there
may be an association. Even conservative researchers who have looked into
these nonthermal effects express concern that this radiation is a "probable"
cause of health problems.
Given that bioeffects
have been seen in exposures as low as 0.000021 W/Kg (Kwee study on Changes
in cell cycle and cell proliferation, 1997) when the FCC limit is 1.6
W/Kg, the safety guidelines need to be re-evaluated. Some scientists,
for instance, are calling for a new measure that would indicate the total
energy absorbed by a tissue, not just the radio frequency energy as it
is with SAR.
Filling the Gap
In the meantime, what do you, as the consumer, do? If the whole tobacco
controversy was any indication, it could take several more years before
there develops any clear consensus about this issue. The everyday cell
phone user cannot afford to wait. Every time you make a call with your
cell phone, radio frequency waves radiate into your head that potentially
put your health at risk.
the concerns of the public becoming more aware of the dangers
of cell phone radiation, there has grown a market to
fill the need for protective solutions. Promising new technologies
that have passed scientific testing are proven to be effective
in preventing biological stress caused by electromagnetic
frequencies. Scientists and health professionals concerned
about public health recommend these scientifically validated
devices and you ought it to yourself to investigate them.
It took two decades
of study, 100 years of consumer use, and untold millions of casualties
before the U.S. Surgeon General's warning label was placed on cigarette
packs. There will come a time when the government becomes satisfied with
the voluminous data it needs to establish the health risks of cell phone
use and set new safety standards. Until then, make sure you do not become
a number in the statistics. Don't wait.
