FDA Consumer Update
The U.S. Food and Drug
Administration Centre for
Devices and Radiological
Health Consumer Update on
Mobile Phones.
1. Do wireless phones pose a
health hazard?
The available scientific
evidence does not show
that any health problems are
associated with using wireless
phones. There is no proof,
however, that wireless phones
are absolutely safe. Wireless
phones emit low levels of
radiofrequency energy (RF)
in the microwave range while
being used. They also emit
very low levels of RF when in
the standby mode. Whereas
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
12
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.
2. What is the FDA's role
concerning the safety of
wireless phones?
Under the law, the 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,
the FDA could require the
manufacturers of wireless
phones to notify users of the
health hazard and to repair,
