A low-pressure mercury-vapor discharge tube floods the inside of a biosafety cabinet with shortwave UV light when not in use, killing microbes on irradiated surfaces. Ultraviolet germicidal irradiation (UVGI) is a disinfection technique employing ultraviolet (UV) light, particularly UV-C (180–280 nm), to kill or inactivate microorganisms ...
There are different types of UV light. There are various kinds of UV light, all originating from the sun (or from UV light-emitting devices.). Only one type of UV light is likely to be effective ...
In this application, the light produced by the lamp is usually filtered to remove as much visible light as possible, leaving just the UV light. Germicidal lamps are also used in waste water treatment in order to kill microorganisms. An EPROM. The small quartz window allows UV light to enter during erasure.

Blood irradiation therapy is an alternative medical procedure in which the blood is exposed to low-level light (often laser light) for therapeutic reasons. [1] The practice was originally developed in the United States, [1] but most recent research on it has been conducted in Germany (by UV lamps) and in Russia (in all variants).
