7 Safety and Warranty
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.
2. 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.
FDA belongs to an interagency working group of the federal agencies that have
responsibility for different aspects of RF safety to ensure coordinated efforts at the federal level.
The following agencies belong to this working group:
