The FCC also regulates the base stations
that the wireless phone networks rely
upon. While these base stations operate
at higher power than do the wireless
phones themselves, the RF exposures that
people get from these base stations are
typically thousands of times lower than
those they can get from wireless phones.
Base stations are thus not the subject
of the safety questions discussed in this
document.
3. What kinds of phones are the
subject of this update?
The term ‘wireless phone’ refers here
to handheld wireless phones with
builtin antennas, often 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 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 which
people use wireless phones, so we don’t
