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 mea-
sure the radio frequency energy
coming from wireless phones?
The Institute of Electrical and Electronic
Engineers (IEEE) is developing a
technical standard for measuring the
radio frequency 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 tissuesimulating 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.
