ultraviolet ray exposure non-ionizing radiation exposure non-ionizing ultraviolet radiation exposure 2012-07-13T01:00:12Z The condition of being subjected to electromagnetic radiation, that is, energy emitted and absorbed by charged particles, which exhibits wave-like behavior as it travels and has both electric and magnetic field components, with wavelengths between 120 and 400 nm. Radiation (i.e. ultraviolet light) at this wavelength does not have sufficient energy to liberate electrons from atoms or molecules although it can induce photochemical reactions, or accelerate radical reactions.
