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 builtin
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
18
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 investigating
the effects of radiofrequency 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 engineered or
treated with cancer causing chemicals so
as to be predisposed to develop cancer
in the absence of RF exposure. Other
studies exposed the animals to RF for up
to 22 hours per day. These conditions are
