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 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
