guidelines that limit RF
exposure. The FCC relies on
the FDA and 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.
3. 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
14
(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.
4. 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.
