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.

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 drugs
