7. 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 (1.6 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 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 Radio
Frequency energy coming
from wireless phones?
The Institute of Electrical and
Electronic Engineers (IEEE) is
developing a technical standard
for measuring the Radio
Frequency (RF) energy 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
