Safety Guidelines
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 telephones
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 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,’
