Non-ionizing radiation refers to a broad range of electromagnetic radiation that does not possess enough energy to ionize an atom or molecule. This type of radiation includes radio waves, microwaves, infrared radiation, visible light, and ultraviolet radiation below a certain energy level. Synonyms for non-ionizing radiation include non-radioactive radiation, non-hazardous radiation, low-frequency radiation, low-energy radiation, non-penetrating radiation, and non-toxic radiation. It is essential to note that while non-ionizing radiation is generally considered to be less dangerous than ionizing radiation, prolonged exposure can still have negative health effects. It is crucial to be aware of non-ionizing radiation sources and to take necessary precautions to reduce exposure where possible.
