1. What kinds of phones are the subject of this update?
The term “wireless phone” refers here to handheld wireless
phones with built-in antennas, often called “cell,” “mobile,” or
“PCS” phones. These types of wireless phones can expose the
user to measurable radiofrequency 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.

2. 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 radiofrequency energy (RF)
