7. 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 (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 milliwatts/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)
