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