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
