research programs around the world. The project has also helped develop
a series of public information documents on EMF issues. The FDA and the
Cellular Telecommunications & Internet Association (CTIA) have a formal
Cooperative Research And Development Agreement (CRADA) to do research
on wireless phone safety. The FDA provides the scientific oversight, obtaining
input from experts in government, industry, and academic organizations.
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
