high levels of RF can produce health effects (by heating tissue), exposure
to low level RF that does not 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 radio
frequency 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:
“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.
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
