produce heating effects causes no known adverse health effects. Many studies
of low level RF exposures have not found any biological effects. Some studies
have suggested that some biological effects may occur, but such findings have
not been confirmed by additional research. In some cases, other researchers
have had difficulty in reproducing those studies, or in determining the reasons
for inconsistent results.
What is FDA's role concerning the safety of wireless phones?
Under the law, FDA does not review the safety of radiation-emitting consumer
products such as wireless phones before they can be sold, as it does with new
drugs or medical devices. However, the agency has authority to take action if
wireless phones are shown to emit radiofrequency energy (RF) at a level that is
hazardous to the user. In such a case, FDA could require the manufacturers of
wireless phones to notify users of the health hazard and to repair, replace or
recall the phones so that the hazard no longer exists.
Although the existing scientific data do not justify FDA regulatory actions, FDA
has urged the wireless phone industry to take a number of steps, including the
following:
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:
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
Section 4A: Safety Guidelines
Support needed research into possible biological effects of RF of the
type emitted by wireless phones;
Design wireless phones in a way that minimizes any RF exposure to the
user that is not necessary for device function; and
Cooperate in providing users of wireless phones with the best possible
information on possible effects of wireless phone use on human health
