The ability of ultraviolet radiation to disinfect water, surfaces and air has been known for over a hundred years. In the last few decades, the primary application across the world has been water disinfection, but it has also matured as a means of disinfection in healthcare and other environments. The COVID-19 pandemic has highlighted the potential for UV radiation to manage the transmission of the disease, both using well-developed technologies and emerging technologies.

Dr Ed Nardell provides an overview of the application of UV for disinfection for a range of pathogens and environments. Dr Ewan Eadie and Dr Kenny Wood describe their research on the application of 222 nm UV excimer lamps for area disinfection.
