federal health and safety agencies. When the phone is located
at greater distances from the user, the exposure to RF is
drastically lower because a person's RF exposure decreases
rapidly with increasing distance from the source. The so-called
"cordless phones, " which have a base unit connected to the
telephone wiring in a 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
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 we
do not 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 long-term exposures, since the
average period of phone use in these studies was around three
years.
