FDA Consumer Update
The U.S. Food and Drug
Administration Centre for Devices
and Radiological Health Consumer
Update on Mobile Phones.
1. 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
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 radio frequency 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
