house, typically operate at far lower power levels, and thus
produce RF exposures far below the FCC safety limits.
4. What are the results of the research done already?
The research done thus far has produced conflicting
results, and many studies have suffered from flaws in
their research methods. Animal experiments investigating
the effects of radiofrequency energy (RF) 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 predisposed 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 we don't know with
certainty what the results of such studies mean for human
health. Three large epidemiology studies have been
published since December 2000. Between them, the
studies investigated any possible association between the
use of wireless phones and primary brain cancer, glioma,
meningioma, or acoustic neuroma, tumors of the brain
or salivary gland, leukemia, or other cancers. None of the
studies demonstrated the existence of any harmful health
effects from wireless phone RF exposures.
However, none of the studies can answer questions about
longterm exposures, since the average period of phone
use in these studies was around three years.
