What is the FDA's role concerning the safety of wireless phones?
Under the law, the 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, the 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, the 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.
