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 pre-disposed to
develop cancer in the absence
of RF exposure. Other studies
exposed the animals to RF for
up to 22 hours per day. These
conditions are not similar to
the conditions under which
people use wireless phones, so
we don’t know with certainty
what the results of such studies
