however, have suggested that low
levels of RF could accelerate the
development of cancer in
laboratory animals. However, many
of the studies that showed
increased tumor development used
animals that had been genetically
engineered or treated with
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, 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
