(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 the 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
