agenda of research needs that has driven the
establishment of new 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 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. 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 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
