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 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
14
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
Commission (FCC) guidelines that limit
radio frequency 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 exposure level for each
model of phone to the FCC. The FCC website
(http://www.fcc.gov/oet/rfsafety) gives
directions for locating the FCC identification
