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 long-term
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 are
needed. Lifetime animal
exposure studies could be
completed in a few years.
However, very large numbers of
animals would be needed to
provide reliable proof of a
cancer promoting effect if one
exists. Epidemiological studies
can provide data that is
directly applicable to human
