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 laboratories
on the same phone. SAR is the
measurement of the amount
of energy absorbed in tissue,
either by the whole body or
