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
investigating the effects of Radio Frequency (RF)
energy exposures characteristic of wireless phones
have yielded conflicting results that often cannot
