is conducted through contracts with independent
investigators.
The initial research will include both laboratory
studies and studies of wireless phone users. The
CRADA will also include a broad assessment of
additional research needs in the context of the
latest research developments around the world.
7. How can I find out how much radio frequency
energy exposure I can get by using my wireless
phone?
All phones sold in the United States must comply
with Federal Communications Commission (FCC)
guidelines that limit radio frequency energy (RF)
exposures. The FCC established these guidelines
in consultation with the FDA and the other federal
health and safety agencies. The FCC limit for RF
exposure from wireless telephones is set at a
Specific Absorption Rate (SAR) of 1.6 watts per
kilogram (1.6 W/kg). The FCC limit is consistent with
the safety standards developed by the Institute
of Electrical and Electronic Engineering (IEEE)
and the National Council on Radiation Protection
and Measurement. The exposure limit takes into
consideration the body's ability to remove heat from
the tissues that absorb energy from the wireless
phone and is set well below levels known to have
effects. Manufacturers of wireless phones must
report the RF exposure level for each model of
phone to the FCC. The FCC website (http://www.fcc.

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
