UVGI can been used to disinfect air, water, and surfaces that are or could be contaminated by bacteria, protozoa, mold spores, fungi, and/or viruses. This document specifically addresses the use of UVGI for disinfection of room air and surfaces. Topics covered include: types of UV radiation; how germicidal UV works to disinfect; UVGI technologies; design and use of GUV systems for disinfection effectiveness; systems comparisons based on type of application, type of pathogen, and means of transmission; system maintenance and performance verification; potential dangers for humans; potential effects on materials and plants; and safety measures and precautions.
