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 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 (RF)
energy 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 Radio Frequency
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 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 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
