interagency working group activities, as well.
FDA shares regulatory responsibilities about 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. FCC relies on
FDA and other health agencies for safety questions about
wireless phones.
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
wireless exposures that people get from these base stations
are typically thousands of times lower than those they get
from wireless phones. Base stations are thus not the subject
of the safety questions discussed in this document.
What kinds of phones are the subject of this
update?
The term "wireless phones" refers here to hand-held wireless
phones with built-in antennas, often called "cell," "mobile," or
"PCS". These types of wireless phones can expose the user
to measurable radio frequency energy (RF) because of the
short distance between the phone and the user's head.
These RF exposures are limited by Federal Communications
Commission safety guidelines that were developed with the
advice of 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
