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