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 confl icting
results, and many studies
have suffered from fl aws
in their research methods.
Animal experiments
investigating the effects of
radiofrequency energy (RF)
exposures characteristic
of wireless phones
have yielded confl icting
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 exposed the
animals to RF for up to
22 hours per day. These
conditions are not similar
to the conditions under
