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.
5. What research is needed to
decide whether RF exposure
from wireless phones poses a
health risk?
A combination of laboratory
studies and epidemiological
studies of people actually
using wireless phones would
provide some of the data that
are needed. Lifetime animal
exposure studies could be
completed in a few years.
However, very large numbers
of animals would be needed
to provide reliable proof of a
cancer promoting effect if one
exists. Epidemiological studies
can provide data that is directly
applicable to human populations,
but ten or more years follow-
up may be needed to provide
answers about some health
effects, such as cancer. This is
because the interval between the
time of exposure to a cancer-
causing agent and the time
tumors develop — if they do —
may be many, many years. The
interpretation of epidemiological
studies is hampered by
difficulties in measuring actual RF
exposure during day-to-day use
of wireless phones. Many factors
affect this measurement, such
as the angle at which the phone
is held, or which model of phone
is used.
6. What is the FDA doing to find
out more about the possible
health effects of wireless
phone RF?
The FDA is working with the
U.S. National Toxicology Program
and with groups of investigators
