Consumer Information on Wireless Phones
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
