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 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 mill-watts/g) of matter. This measurement is used to determine whether a
wireless phone complies with safety guidelines.
8. 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 (1.6W/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.
