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.

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
