cancer causing chemicals so as 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 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, gioma, 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.
11.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
