energy from the wireless device and is set well below levels known to
have effects. Manufacturers of wireless devices must report the RF
exposure level for each model of wireless device to the FCC. The FCC
website (http://www.fcc.gov/oet/rfsafety) gives directions for locating the
FCC identification number on your wireless device so you can find your
wireless device’s RF exposure level in the online listing.
8. What has the FDA done to measure the Radio Frequency energy
coming from wireless devices?
The Institute of Electrical and Electronic Engineers (IEEE) is developing a
technical standard for measuring the Radio Frequency (RF) energy
exposure from wireless devices 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 device 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 wireless device.
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 device complies with safety guidelines.
9. What steps can I take to reduce my exposure to Radio Frequency
energy from my wireless device?
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 Radio Frequency (RF) energy. Since time is a key factor in
how much exposure a person receives, reducing the amount of time spent
using a wireless device will reduce RF exposure. If you must conduct
extended conversations by wireless device every day, you could place
more distance between your body and the source of the RF, since the
