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(RF) energy. 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 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.
7. How can I find out how much radio
frequency energy exposure I can get by
using my wireless phone?
All phones sold in the United States must
comply with Federal Communications
