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 phone so you can find your
phone’s RF exposure level in the
online listing.
8. What has the FDA done to
measure the radiofrequency
energy coming from wireless
phones?
The Institute of Electrical and
Electronic Engineers (IEEE) is
developing a technical standard
for measuring the radiofrequency
energy (RF) exposure from
wireless phones and other
wireless handsets with the
participation and leadership of
FDA scientists and engineers.
The standard, ‘Recommended
Practice for Determining the
Spatial- Peak Specific Absorption
Rate (SAR) in the Human Body
Due to Wireless Communications
Devices: Experimental Techniques,’
sets forth the first consistent test
methodology for measuring the
rate at which RF is deposited
in the heads of wireless phone
users. The test method uses a
tissuesimulating model of the
human head. Standardized SAR
test methodology is expected to
greatly improve the consistency of
measurements made at different
Safety Guidelines
