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 long-term exposures, since

5. What research is needed to decide whether RF exposure
a
from wireless phones poses a health risk?
nce
A combination of laboratory studies and epidemiological studies of
e a
people actually using wireless phones would provide some of the
ally
data that are needed. Lifetime animal exposure studies could be
ures
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
nd
follow-up may be needed to provide answers about some health

effects, such as cancer. This is because the interval between the
y
time of exposure to a cancer-causing agent and the time tumors
develop — if they do — may be many, many years. The
er
interpretation of epidemiological studies is hampered by difficulties
hat
in measuring actual RF exposure during day-to-day use of wireless
n
phones. Many factors affect this measurement, such as the angle at
d
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
ons
with groups of investigators around the world to ensure that high
with
priority animal studies are conducted to address important questions
alth.
about the effects of exposure to radio frequency energy (RF).
