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 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?
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.
