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 Fields (EMF)
Project since its inception in 1996. An influential result of
this work has been the development of a detailed agenda
of research needs that has driven the establishment of
