For Your Safety
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.
