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; 

 

“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: 

 

“National Institute for Occupational Safety and Health 

 

“Environmental Protection Agency 

 

“Federal Communications Commission 

 

“Occupational Safety and Health Administration 

 

“National Telecommunications and Information Administration 

The National Institutes of Health participates in some interagency working 

group activities, as well. 
FDA shares regulatory responsibilities for wireless phones with the Federal 
Communications Commission (FCC). All phones that are sold in the United 
States must comply with FCC safety guidelines that limit RF exposure. 
FCC relies on FDA and other health agencies for safety questions about 

wireless phones. 
FCC also regulates the base stations that the wireless phone networks 
rely upon. While these base stations operate at higher power than do the
