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.
These conditions are not similar to the
conditions under which people use wireless
phones, so we don't know with certainty
what the results of such studies mean for
human health. Three large epidemiology
studies have been published since
December 2000. Between them, the studies
investigated any possible association
between the use of wireless phones and
primary brain cancer, glioma, meningioma,
or acoustic neuroma, tumors of the brain or
salivary gland, leukemia, or other cancers.
None of the studies demonstrated the
existence of any harmful health effects from
wireless phone RF exposures. However,
none of the studies can answer questions
about long-term exposures, since the
average period of phone use in these studies
was around three years.
