Health and Sanitization through UV Lighting

Health and Sanitization through UV Lighting How do you go about determining the light levels and exposures needed to sufficiently sanitize a surface? With the SARS-CoV-2 pandemic, a strong demand for UV disinfecting lamps has developed. UV light, especially the UVC region from 255nm to 265nm, has been shown to render viruses noninfectious by destroying their genetic material , DNA and RNA. In general, a dosage of 20 to 100 mJ/cm² of UVC light is usually sufficient to destroy most bacteria and viruses, including coronaviruses like SARS-CoV-2. How do you go about determining the light levels...
