The National Institutes of Health
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
