What kinds of phones are the subject of this update? The term "wireless phones" refers here to hand-held wireless phones with built-in antennas, often called "cell," "mobile," or "PCS". 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 phone wiring in a house, typically operate at far lower per levels, and thus produce RF exposures far below the FCC safety limits. What are the results of the research done already? The research done thus far has produced conflicting results, and many studies have suffered from flaws in their research methods. Animal experiments investigating the effects of radio frequency energy (RF) exposures characteristic of wireless phones have yielded conflicting results that often cannot be repeated in other laboratories. A few animal studies, however, have suggested that low levels of RF could Accelerate the development of cancer in laboratory animals. However, many of the studies that showed increased tumor development used animals that had been genetically 136 Health and Safety Information

What kinds of phones are the subject of this update?
The term “wireless phones” refers here to hand-held
wireless phones with built-in antennas, often called “cell,”
“mobile,” or “PCS”. 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 phone wiring in a house, typically

exposures far below the FCC safety limits.
What are the results of the research done already?
The research done thus far has produced conflicting
results, and many studies have suffered from flaws in
their research methods. Animal experiments
investigating the effects of radio frequency energy (RF)
exposures characteristic of wireless phones have yielded
conflicting results that often cannot be repeated in other
laboratories. A few animal studies, however, have
suggested that low levels of RF could Accelerate the
development of cancer in laboratory animals. However,
