Consumer Information on Wireless Phones
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 radio frequency 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
pre-disposed to develop cancer in 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 phones RF exposures. However,
none of the studies can answer questions about long-term exposures, since
the average period of phone use in these studies was around three years.
