additional research. In some cases, other researchers have had difficulty in reproducing those
studies, and/or determining the reasons for inconsistent results.
3. What are the results of the research done already?
The research conducted 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 it is largely unknown what the results of such
studies mean for human health and safety. Three large epidemiology studies have been
