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 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 December 2000. These
studies investigated possible associations between the use of wireless phones and primary
