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.
If you must conduct extended
conversations by wireless
phone every day, you could
place more distance between
your body and the source of
