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 seguridad y salud laborales)
•
Occupational Safety and Health Administration
•
National Telecommunications and Information Administration
•
The National Institutes of Health participates in some interagency working group activities, as well.
The 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. The FCC relies on the FDA and other health agencies for safety questions about wireless phones.
The FCC also regulates the base stations that the wireless phone networks rely upon. While these base stations
operate at higher power than do the wireless phones themselves, the RF exposures that people get from these
base stations are typically thousands of times lower than those they can get from wireless phones. Base stations
are thus not the subject of the safety questions discussed in this document.
