2. 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
radio frequency 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.
3. 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
