UVCBereich
UVCBereich is the German designation for the ultraviolet‑C portion of the electromagnetic spectrum. It encompasses wavelengths between 100 nm and 280 nm, with the most biologically relevant band lying from about 200 nm to 280 nm. In atmospheric science, the UVCBereich is largely absorbed by the Earth’s ozone layer and by atmospheric oxygen, preventing most of it from reaching the surface. Consequently, natural UVC exposure at ground level is negligible, and the body is not routinely exposed to this high‑energy radiation.
In laboratory and industrial settings, UVC light is produced by mercury vapour lamps and more recently by
The high photon energy of the UVCBereich also poses significant safety risks. Direct exposure can cause erythema
