Safety
phone RF exposures. However, none of the studies can answer questions
about long-term 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
ten 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 Radio Frequency (RF) energy.
The FDA has been a leading participant in the World Health Organization
International Electro Magnetic 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 new
research programs around the world. The project has also helped develop a
series of public information documents on EMF issues.
The FDA and the Cellular Telecommunications & Internet Association
(CTIA) have a formal Cooperative Research And Development Agreement
(CRADA) to do research on wireless phone safety. The FDA provides the
