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
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
is conducted through contracts with
independent investigators. The initial
research will include both laboratory
studies and studies of wireless
phone users. The CRADA will
also include a broad assessment
of additional research needs in
the context of the latest research
developments around the world.
