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 phones?
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 health.
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.
FDA shares regulatory responsibilities for wireless phones with the Federal
Communications Commission (FCC). All phones that are sold in the United
States must comply with FCC safety guidelines that limit RF exposure. FCC
relies on FDA and other health agencies for safety questions about wireless
phones.
