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 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.
