For Your Safety
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 Radio Frequency
(RF) energy 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. Animal experiments
