Standardized SAR test methodology is expected to
greatly improve the consistency of measurements made
at different laboratories on the same phone. SAR is the
measurement of the amount of energy absorbed in
tissue, either by the whole body or a small part of the
body. It is measured in watts/kg (or mill-watts/g) of matter.
This measurement is used to determine whether a
wireless phone complies with safety guidelines.
8. 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 (RF) energy 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 phones is
set at a Specific Absorption Rate (SAR) of 1.6 watts per
kilogram (1.6W/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/cgb/cellular.html)
gives directions for locating the FCC identification
number on your phone, so you can find your phone’s RF
exposure level in the online listing.
