Safety Guidelines 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 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. 97

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 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 pre-
disposed to develop cancer in the absence
of RF exposure. Other studies exposed the
animals to RF for up to 22 hours per day.
