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 Radio
Frequency (RF) energy 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 do not 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.
