while operating microwave ranges (which also emit very low levels of RF when they
are in standby mode). While high levels of RF can produce health effects (by
heating tissue), exposure to low-level RF that does not produce heating effects
results in no known adverse health effects. Many studies of low-level RF exposures
have not uncovered any biological effects. Although some studies have suggested
that some biological effects may occur, such findings have not been confirmed by
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
