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
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 published since
