“UVC with a wavelength of 222 nm had a potent germicidal effect on vegetative bacterial cells, yeast and viruses, and was as efficient as 245-nm UVC. In addition, 222-nm UVC had a more potent germicidal effect on bacterial endospores compared with 254-nm UVC. The fungicidal effect of 222-nm UVC against fungal spores and hyphae was weaker than that of 254-nm UVC.”
