Safety Guidelines
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,’
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
tissue-simulating 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 a small part of
the body. It is measured in watts/kg (or milliwatts/g)
of matter. This measurement is used to determine
whether a wireless phone complies with safety
guidelines.
9.What steps can I take to reduce my exposure to
radiofrequency energy from my wireless phone?
If there is a risk from these products - and at this point
we do not know that there is - it is probably very small.
But if you are concerned about avoiding even potential
risks, you can take a few simple steps to minimize your
