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.
