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
phones 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.
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
