2. Do wireless phones pose a health hazard?
Current scientific evidence does not show that any health problems are associated
with using wireless phones. There is no proof, however, that wireless phones are
absolutely safe. Wireless phones emit low levels of Radio Frequency (RF) energy 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 similar to the
