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.
