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 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.
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
around the world to ensure that
