detailed 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 device 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 device 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 device?
All devices 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 devices 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 device
and is set well below levels known to have effects. Manufacturers of wireless
devices must report the RF exposure level for each model of device to the
FCC. The FCC website (
http://www.fcc.gov/oet/rfsafety
) gives directions for
locating the FCC identification number on your device so you can find your
device’s RF exposure level in the online listing.
8. What has the FDA done to measure the Radio Frequency
energy coming from wireless devices?
The Institute of Electrical and Electronic Engineers (IEEE) is developing a
technical standard for measuring the Radio Frequency (RF) energy exposure
from wireless devices 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
