other health agencies for safety questions about wireless phones.
the Fcc also regulates the base stations that the wireless phone
networks rely upon. While these base stations operate at higher
power than do the wireless phones themselves, the rF exposures
that people get from these base stations are typically thousands
of times lower than those they can get from wireless phones. Base
stations are thus not the subject of the safety questions discussed
in this document.
. 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
Fcc safety guidelines that were developed with the advice of the
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 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 radiofrequency
energy (rF) exposures characteristic of wireless phones have
