Consumer Information on Wireless
Phones
The U.S. Food and Drug Administration (FDA) has 
published a series of Questions and Answers for 
consumers relating to radio frequency (RF) exposure 
from wireless phones. The FDA publication includes 
the following information:
What kinds of phones are the subject of
this update?
The term wireless phone refers here to hand-held 
wireless phones with built-in antennas, often called 
"cell," "mobile," or "PCS" phones. These types of 
wireless phones can expose the user to measurable 
radio frequency energy (RF) because of the short 
distance between the phone and the user's head. 
These RF exposures are limited by Federal 
Communications Commission safety guidelines that 
were developed with the advice of FDA and other 
federal health and safety agencies.
When the phone is located at greater distances from 
the user, the exposure to RF is drastically lower 
because a person's RF exposure decreases rapidly 
with increasing distance from the source. The so-
called "cordless phones," which have a base unit 
connected to the telephone wiring in a house, 
typically operate at far lower power levels, and thus 
produce RF exposures well within the FCC's 
compliance limits.
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 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.
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
