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
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 number on your
