Safety
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 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
