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 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.
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 exposure to
radiofrequency energy (RF). Since time is a key factor in how much exposure a
person receives, reducing the amount of time spent using a wireless phone will
reduce RF exposure.
