experiments investigating the effects of Radio
Frequency (RF) energy 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 do not 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
