lower power levels, and thus produce RF
exposures far below the FCC safety limits.
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 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
74
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 effect if
