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
high priority animal studies are
conducted to address important
questions about the effects
