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 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.
