Figure 4. (a) Experimental setup for detecting the reflected far-UVC light on the steel and the glass surfaces; (b) Reflected far-UVC intensity at different angles and distances, α (1-3) = 30°, 45°, 60°, r (1-3) = 10, 20, 30 cm, respectively; (C) Comparison of the reflected far-UVC intensity between glass and steel surfaces at different angles; (d) Schematic of the inactivation of microorganisms by far-UVC exposure on the glass and the steel surfaces
