’, ‘mobile’, or ‘PCS’ phones.
These types of wireless
phones can expose the user
to measurable radiofrequency
energy (RF) because of the
short distance between
the phone and the user’s
head. These RF exposures
are limited by FCC safety
guidelines that were developed
with the advice of the FDA
and other federal health and
safety agencies. When the
phone is located at greater
distances from the user, the
exposure to RF is drastically
lower because a person’s RF
exposure decreases rapidly
with increasing distance from
the source. The so-called ‘
cordless phones,’ which
have a base unit connected
to the telephone wiring in a
house, typically operate at far
lower power levels, and thus
produce RF exposures far
below the FCC safety limits.
4. What are the results of the
research done already?
The research done thus far
has produced conflicting
results, and many studies have
suffered from flaws in their
research methods. Animal
experiments investigating
the effects of radiofrequency
energy (RF) exposures
characteristic of wireless
phones have yielded conflicting
results that often cannot be
repeated in other laboratories.
A few animal studies, however,
have suggested that low
levels of RF could accelerate
the development of cancer in
laboratory animals. However,
many of the studies that
showed increased tumor
development used animals
that had been genetically
engineered or treated with
cancer causing chemicals
so as to be predisposed to
develop cancer in the absence
of RF exposure. Other studies
