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.
