7. How can I fi nd
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 Specifi c 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
identifi cation number on
your phone so you can fi nd
your phone’s RF exposure
level in the online listing.
