FDA Consumer Update
The U.S. Food and Drug Administration’s Center for
Devices and Radiological Health Consumer Update on
Mobile Phones.
1. 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
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.
