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 prob-
ably 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 wire-
less phone will reduce RF exposure.
• If you must conduct extended conversations
by wireless phone every day, you could place
more distance between your body and the
source of the RF, since the exposure level drops
off dramatically with distance. For example,
you could use a headset and carry the wireless
phone away from your body or use a wireless
phone connected to a remote antenna.

The FCC website (http://www.fcc.gov/oet/rfsafety)
gives directions for locating the FCC identifica-
tion 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) expo-
sure 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 measure-
ments 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.
