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.
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.
