Far-UVC radiation for disinfection in the presence of people in public indoor spaces through unshielded open radiation sources has been promoted for several years, claiming to be a simple solution to reduce infections from airborne pathogens such as bacteria and viruses. This literature review summarizes the existing research on the effectiveness of far-UVC radiation for inactivating pathogens, as well as potential risks to skin and eyes associated with exposure to far-UVC radiation. Further, it discusses radiation protection aspects of using far-UVC radiation in the presence of people, and addresses possible effects of far-UVC radiation on the human environment as well. The literature review shows that despite its antimicrobial and antiviral effectiveness, there is so far no sufficient evidence that far-UVC radiation can be used for disinfection in the presence of people in public indoor spaces without risks for humans and the environment. There are particular concerns about the safety of vulnerable groups such as children, the elderly and people with pre-existing medical conditions. The authors recommend further and extended studies in this field concerning potential risks of far-UVC radiation.
