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.
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.
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
very large numbers of animals
would be needed to provide reliable
proof of a cancer promoting effect if
one exists. Epidemiological studies
