98  Consumer Information on Wireless Phones 

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 web site. 

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.
