Consumer Information on Wireless Phones

The U.S. Food and Drug Administration (FDA) has published a series of Questions and
Answers for consumers relating to radio frequency (RF) exposure from wireless phones.
The FDA publication includes the following information:
What kinds of phones are the subject of this update?
The term wireless phone refers here to hand-held wireless phones with built-in antennas,
often called "cell," "mobile," or "PCS" phones. These types of wireless phones can
expose the user to measurable radio frequency energy (RF) because of the short
distance between the phone and the user¡¯s head. These RF exposures are limited by
Federal Communications Commission safety guidelines that were developed with the
advice of FDA and other federal health and safety agencies. When the phone is located
at greater distances from the user, the exposure to RF is drastically lower because a
person¡¯s RF exposure decreases rapidly with increasing distance from the source. The
so-called ¡°cordless phones,¡± which have a base unit connected to the telephone wiring
in a house, typically operate at far lower power levels, and thus produce RF exposures
well within the FCC¡¯s compliance limits.
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 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
