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. 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 longterm exposures, since the average period
of phone use in these studies was around three years.
5. What research is needed to decide whether RF
exposure from wireless phones poses a health
risk?
A combination of laboratory studies and
epidemiological studies of people actually using
wireless phones would provide some of the data that
is needed. Lifetime animal exposure studies could
