Section 4: Safety and Terms & Conditions

The U.S. Food and Drug Administration (FDA) provides consumer information on 

wireless phones at: http://www.fda.gov/cellphones/qa.html

Following are safety-related questions and answers discussed at this website.

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 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.

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:

䢇

Support needed research into possible biological effects of RF of the type 
emitted by wireless phones;

䢇

Design wireless phones in a way that minimizes any RF exposure to the user 
that is not necessary for device function; and 

䢇

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:

䢇

National Institute for Occupational Safety and Health

䢇

Environmental Protection Agency

䢇

Federal Communications Commission
