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
Under the law, 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, 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, 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
Cooperate in providing users of wireless phones with the best possible
information on possible effects of wireless phone use on human
FDA belongs to an interagency working group of the federal
agencies that have responsibility for different aspects of RF
safety to ensure coordinated efforts at the federal level. The
following agencies belong to this working group:
National Institute for Occupational Safety and Health
Environmental Protection Agency
Federal Communications Commission
Occupational Safety and Health Administration
National Telecommunications and Information Administration
The National Institutes of Health participates in some interagency
working group activities, as well.
