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 to human
populations, but 10 or more years follow-up
may be needed to provide answers about
some health effects, such as cancer.
