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 Agreement
(CRADA) to do research on
