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 (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
