RF Radiation Information RF Radiation Profile Radio Frequency (RF) is a frequency of electromagnetic radiation in the range at which radio signals are transmitted. RF technology is widely used in communication, medicine, food processing and other fields. It may generate radiation during use. RF Radiation Safety In order to ensure user health, experts from relevant industries including science, engineering, medicine and health work with international organizations to develop standards for safe exposure to RF radiation. These standards consist of: ● ● United States Federal Communications Commission, Code of Federal Regulations; 47CFR part 2 sub-part J; ● ● American National Standards Institute (ANSI)/ Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1992; ● ● Institute of Electrical and Electronic Engineers (IEEE) C95. 1 – 1999; ● ● International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998; FCC Regulations Federal Communication Commission (FCC) requires that all radio communication products should meet the requirements set forth in the above standards before they can be marketed in the U.S, and the manufacturer shall post a RF label on the product to inform users of operational instructions, so as to enhance their occupational health against exposure to RF energy. *
