FDA Consumer Update
The U.S. Food and Drug Administration’s Center for Devices and
Radiological Health Consumer Update on Mobile Phones:
Do wireless phones pose a health hazard?
The available scienti
fi
c 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 (RF) energy
in the microwave range while being used. They also emit very low
levels of RF when in 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
fi
ndings have not been
con
fi
rmed by additional research. In some cases, other researchers
have had di
ffi
culty in reproducing those studies, or in determining
the reasons for inconsistent results.
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 (RF) energy at a level
