This book is a comprehensive source for technical information regarding ultraviolet germicidal irradiation (UVGI) and its application to air and surface disinfection for the control of pathogens and allergens. The primary focus is on airborne microbes and surface contamination applications for hospitals, commercial facilities, and residential homes.

All aspects of UVGI systems, including design methods, sizing methods, modeling, safety, installation, testing, guidelines, and disinfection theory are addressed in detail. An extensive database of over six hundred UV rate constant studies is included as well as tabular performance data for UV lamps and products. Providing this information in one single source simplifies the design and installation of UVGI systems, helps guarantee effective performance of new systems, and facilitates their use on a wide scale for the purpose of improving human health. This book is organized to provide systematic coverage of all related issues and will serve equally well as both a textbook and a handbook for general reference.
