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 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
Cooperate in providing of wireless phones
with the best possible information on
possible effects of wireless phone use on
human health.
The 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
Occupational Safety and Health
Administration (Administración de la
