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.
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 formal Cooperative
Research and Development Agreement (CRADA) to
do research on wireless phone safety. FDA provides the
scientific oversight, obtaining input from experts in
government, industry, and academic organizations.
CTIA-funded research is conducted through contracts
to independent investigators. The initial research will
include both laboratory studies and studies of wireless
phone users. The CRADA will also include a broad
