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 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
