Radiofrequency (RF) Radiation. Biological effects that result from heating of tissue by RF energy are often referred to as "thermal" effects. It has been known for many years that exposure to very high levels of RF radiation can be harmful due to the ability of RF energy to rapidly heat biological tissue.How does radio frequency work?
Radio waves maintain a uniform frequency and amplitude at all times. As a result, data can be placed into radio waves through amplitude and frequency modulation.The signals carried by radio waves are received by antennas within cell phones, televisions and radios.What is the frequency of a radio?
radio frequency. noun. : any of the electromagnetic wave frequencies that lie in the range extending from below 3 kilohertz to about 300 gigahertz and that include the frequencies used for communications signals (as for radio and television broadcasting and cell-phone and satellite transmissions) or radar signals.
