CTIA-funded research 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 (RF) energy
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 phones 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.gov/oet/rfsafety) gives directions for
locating the FCC identification number on your
phone so you can find your phone’s RF exposure
level in the online listing.
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 (RF) energy
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
