• Cooperate in providing users of wireless phones with the best possible
information on possible effects of wireless phone use on human health.
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.
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. 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 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 radio frequency energy (RF)
because of the short distance between the device 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 device 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-
