Safety Guidelines
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
radiationemitting 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
78
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:
v
Support needed research into
possible biological effects of RF
of the type emitted by wireless
phones;
v
Design wireless phones in a way
that minimizes any RF exposure to
the user that is not necessary for
device function; and
v
Cooperate in providing users of
wireless phones with the best
possible information on possible
effects of wireless phone use on
human health.
