phone use in these studies was around

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 FDA doing to find out more
about the possible health effects of
wireless phone RF?
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).
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.
FDA and the Cellular Telecommunications
& Internet Association (CTIA) have a
