Radiofrequency (RF) radiation is at the low-energy end of the electromagnetic spectrum and is a type of non-ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to ionize (remove charged particles such as electrons).icrowave ovens work by using very high levels of a certain frequency of RF radiation (in the microwave spectrum) to heat foods. When microwaves are absorbed by food containing water, it causes the water molecules to vibrate. This produces heat.
The Electromagnetic Spectrum. The electromagnetic spectrum consists of the full range of known electromagnetic waves, including gamma rays, X-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves.All of these are produced by various forms of oscillating charges or currents.amma Rays Gamma rays are the most energetic known form of electromagnetic radiation, with frequencies of 3*10 19 Hz (30 EHz) or higher and wavelengths of 10 -11 m (10 pm) or lower. They are produced from the decay of excited nuclei of radioactive elements.
