Research and Development Agreement (CRADA) to
do research on wireless phone safety. FDA provides
the scientific oversight, obtaining input from experts in
government, industry, and academic organizations.
CTIA-funded research is conducted through contracts
to 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 radiofrequency
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 radiofrequency energy (RF) exposures. FCC
established these guidelines in consultation with 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 FDA done to measure the radiofrequency
energy coming from wireless phones ?
The Institute of Electrical and Electronic Engineers
(IEEE) is developing a technical standard for
measuring the radiofrequency energy (RF) exposure
from wireless phones and other wireless handsets
with the participation and leadership of FDA scientists
anring 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
