The properties of ultraviolet light depend on the wavelength, and the UV spectrum varies across different sources. Let's discuss the sources of ultraviolet light and how to use them to maximize their bactericidal effects while minimizing the risks of undesirable biological effects. Fig. 1. The photo does not show disinfection with UVC radiation, as one might think, but rather training in the use of protective suits, identifying luminescent spots of simulated bodily fluids under UVA rays. UVA […]
