Animal experiments
investigating the effects of
radiofrequency energy (RF)
exposures characteristic of
wireless phones have yielded
conflicting results that often
cannot be repeated in other
laboratories. A few animal
studies, 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.

decide whether RF exposure
from wireless phones poses
a health risk?
