What kinds of phones are the subject of this
update?
The term “wireless phones” refers here to hand-held wireless
phones with built-in antennas, often called “cell,” “mobile,” or
“PCS”. These types of wireless phones can expose the user to
measurable radio frequency energy (RF) because of the short
distance between the phone and the user’s head. These RF
exposures are limited by Federal Communications
Commission safety guidelines that were developed with the
advice of 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 phone wiring in a house, typically
operate at far lower per levels, and thus produce RF
exposures far below the FCC safety limits.
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 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 absence of RF exposure.
Other studies exposed the animals to RF for up to 22 hours
per day.
