From: Far-UVC (222Â nm) efficiently inactivates an airborne pathogen in a room-sized chamber

Percentage of viable airborne S. aureus remaining plotted on a logarithmic y-axis against time after switch-on of the Far-UVC sources for three different exposure scenarios—high (top), medium (middle) and low (bottom). Note that the pathogen was continuously released into the room throughout the experiment: The studies were undertaken using either a single central lamp (green, square data points, dashed lines) or all five Far-UVC lamps (blue, circular data points, solid lines).
