Effects of Surface Reflection of Ultraviolet Disinfecting Light

Ben Ma et al research paper at Science Direct discussing UVC surface disinfection effects when UVC light is reflected from surface to be cleaned. Purchase full PDF at: Abstract The COVID-19 pandemic has promoted interest in using devices emitting ultraviolet-C (UVC) irradiation (200–280 nm) for surface disinfection to reduce pathogen transmission, especially in occupied public spaces. While UVC devices have been shown to be highly effective against various pathogens, there are safety concerns when using conventional UVC devices for surface disinfection, including human exposure of reflected UVC irradiation and ozone generation. Emerging Far UVC devices (emitting at 200–230 nm),…
