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 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
