Understanding the effect of ultraviolet light intensity on disinfection performance through the use of ultraviolet measurements and simulation

Abstract

We measured the disinfection of MRSA and Clostridium difficile spores using an ultraviolet C (UV-C) device, and we correlated those results to measurements and computer simulations of UV-C surface intensity. The results demonstrate both large differences in UV light intensity across various surfaces and how this leads to significant differences in disinfection.
