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 radiofrequency
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 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 radiofrequency energy exposure I can get by
using my wireless phone?
All phones sold in the United States must comply with Federal Communications
Commission (FCC) guidelines that limit radiofrequency energy (RF) exposures. The
FCC established these guidelines in consultation with the FDA and the other federal
health and safety agencies. The FCC limit for RF exposure from wireless telephones
is set at a Specific Absorption Rate (SAR) of 1.6 watts per kilogram (1.6 W/kg). The
FCC limit is consistent with the safety standards developed by the Institute of Electrical
and Electronic Engineering (IEEE) and the National Council on Radiation Protection and
Measurement. The exposure limit takes into consideration the body's ability to remove
heat from the tissues that absorb energy from the wireless phone and is set well below
levels known to have effects. Manufacturers of wireless phones must report the RF
Safety Guidelines
