4. What are the results of the
research done already?
The research done thus far
has produced conflicting
results, and many studies
have suffered from flaws in
their research methods.
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 predisposed 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
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.
