participates in some interagency
working group activities, as
well. The FDA shares regulatory
responsibilities for wireless phones
with the Federal Communications
Commission (FCC). All phones that
are sold in the United States must
comply with FCC safety guidelines
that limit RF exposure. The FCC
relies on the FDA and other health
agencies for safety questions about
wireless phones. 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 built-in 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.
