SAFETY
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 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 assessment
of additional research needs in the context of the latest research
developments around the world.
