Abstract

We measured the amount of UV-C light (254 nm) achieved on hospital surfaces using a modified emitter and competing placement strategies. An autonomous UV-C strategy improved exposure on surfaces that were distant, angled, or shadowed to the nonautonomous strategies, leading to significantly higher overall UV-C dosages.
