A Method of Ultraviolet-C Surface Irradiation Simulation and Evaluation

See — Ultraviolet germicidal irradiation (UVGI) is getting popular as a surface disinfection method. UVGI inactivates pathogens by exposing surfaces to high-power ultraviolet-C (UVC) radiation. The disinfection performance is commonly quantified by the radiation dose received by the targeted surfaces and the irradiation coverage. The radiation dose received by a point is commonly sensed by installing a discrete sensor at that point. Thus, to measure coverage, one has to use multiple sensors or take repeated measurements, which leads to the measurements being costly and impractical. We present a method of UV-C irradiation simulation by modeling the UVGI system…
