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 (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 (1.6 |
| W/kg). The FCC limit is consistent with the safety |
| standards developed by the Institute of Electrical and |
| Electronic Engineering (IEEE) and the National |
S | Council on Radiation Protection and Measurement. |
a f e t | The exposure limit takes into consideration the body’s |
y | 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 (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.
