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.
