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
