The FDA belongs to an interagency working group of the federal
agencies that have responsibility for different aspects of RF safety
to ensure coordinated efforts at the federal level. The following
agencies belong to this working group:
• National Institute for Occupational Safety and Health
• Environmental Protection Agency
• Federal Communications Commission
• Occupational Safety and Health Administration
• National Telecommunications and Information Administration
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 hand-held 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 Federal Communications
Commission 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 FCC safety limits.
