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 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 radio
frequency 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
