Section 4: Safety Guidelines and Warranty Information
120 4A: Safety
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.
21. 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 radio frequency 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.
22. What steps can I take to reduce my exposure to radio
frequency energy from my wireless phone?
If there is a risk from these products--and at this point we do not know
that there is--it is probably very small. But if you are concerned about
