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.
