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 stand-by 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 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:
- 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.
