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 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?
