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 of
exposure to radiofrequency
energy (RF). The FDA has been
a leading participant in the
World Health Organization
International Electromagnetic
