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
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.
