UV-C (also called germicidal UV) is part of the ultraviolet spectrum that can inactivate pathogens like bacteria and viruses. 7 nm (nanometers), they have germicidal effect on bacteria, viruses, yeasts and molds. com provide a large selection of promotional uv germicidal lamps on sale at cheap price and excellent crafts. UVC Germicidal Bulb - DANGEROUS But Useful Ultraviolet Light. Dose-response plots show that vaccinia virus susceptibility increased with decreasing RH. Ultraviolet radiation 3. A number of parameters were evaluated during the study. In the wavelength range of 253. coli and bacterial spores. The degree of inactivation of microorganisms by ultraviolet radiation is causally related to the UVC dose applied.
