called 'cell' , '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 pre-
disposed to develop cancer in
the absence of RF exposure.
