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,
28
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 radio frequency
energy (RF). The FDA has
been a leading participant in
the World Health Organization
International Electromagnetic
Fields (EMF) Project since its
inception in 1996. An influential
