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?
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;
