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
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 scientific oversight, obtaining
input from experts in government, industry, and
academic organizations. CTIA-funded research
