Safety Guidelines
7. How can I find out how much radiofrequency 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 radiofrequency 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 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 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.
