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 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 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
30
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
