Abstract
There is global interest in both the beneficial and detrimental health effects of ultraviolet-C (UVC) radiation in the wavelength range 200-230 nm (known as Far-UVC). Technology using Far-UVC is proposed as a highly effective control measure for reducing the transmission of COVID-19. Far-UVC, and other wavelengths of UVC, are well-known to efficiently inactivate pathogens in air and on surfaces. Although studies have shown irradiation of skin with 254 nm UV results in DNA damage in the epidermal basal layer, irradiation with Far-UVC (222 nm) shows minimal DNA damage and only in the granular layer, which is comprised of non-proliferating keratinocytes.
