3. What kinds of phones
are the subject of this
update?
The term "wireless phone" refers
here to handheld wireless phones
with built-in antennas, often
called "cell", "mobile", or "PCS"
phones. These types of wireless
phones can expose the user to
measurable Radio Frequency
(RF) energy 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
154
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 Radio
Frequency (RF) energy 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
