Web222nm. Ultraviolet radiation C (UVC) is defined as 100 - 280 nm wavelengths UV. UVC from solar UV cannot reach the surface of the earth, because this range of UV is absorbed by the ozone layer. Conventional germicidal UVC light (254nm wavelength) can be used to disinfect unoccupied spaces such as empty hospital rooms or empty subway cars, but ... WebUltraviolet (UV) radiation is a form of non-ionizing radiation that is emitted by the sun and artificial sources, such as tanning beds. The beneficial effects of UV radiation include the production of a vital nutrient, vitamin D; however, overexposure may present risks. Sunburn, premature aging, and skin cancer are all risks to overexposure.
