Different wavelength of UV light, measured here in nanometers, can penetrate skin down to different layers. The farther down into the skin these wavelengths go, the more harm they can cause.

The role of UV disinfection today
UV light in various forms has been used widely since the early 20th century to disinfect water, air and surfaces. As early as the 1940s, it was used to reduce the transmission of tuberculosis in hospitals and classrooms, by shining the light at the ceiling to disinfect air as it circulated throughout the room. Today, it’s used not only in hospitals, but in some public bathrooms and airplanes when there are no people in those spaces.

In a recent White Paper published by the International UV Association, “Far UV-C Radiation: Current State-of Knowledge,” which accompanies the new study, Linden and co-authors argue that this safer wavelength of Far UV-C light could serve as a key mitigation measure against the current and future pandemics, in addition to improved ventilation, mask wearing and vaccination.

Linden imagines systems that could either cycle on and off in indoor spaces to routinely clean the air and surfaces, or create an ongoing, invisible barrier between teachers and students, customers and service workers, and people in spaces where social distancing is not possible, to disinfect the air.

UV light disinfection can even rival the positive effects of improved indoor ventilation by providing the equivalent protection of increased air changes per hour within a room. It’s also much cheaper to install UV lights than to upgrade an entire HVAC system.
