wireless phones. There is no proof,
however, that wireless phones are
absolutely safe. Wireless phones
emit low levels of radiofrequency
energy (RF) in the microwave range
while being used. They also emit
very low levels of RF when in the
standby 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.
2. What is the FDA's role concerning
the safety of wireless phones?
Under the law, the 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
radiofrequency energy (RF) at a level
that is hazardous to the user. In such
a case, the 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,
the 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
