FDA CONSUMER UPDATE
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. FCC
established these guidelines in consultation with 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 consider-
ation the body’s ability to remove heat from the tis-
sues 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 cellular telephone so you can find
your phone’s RF exposure level in the online listing.
