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.
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 10 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.
