Upper air ultraviolet germicidal irradiation (UVGI), in combination with appropriate room ventilation, is increasingly being used as a method to reduce transmission of airborne infectious diseases such as tuberculosis. UVGI luminaires appropriate for upper room air disinfection are installed above eye level and designed to limit vertical emission spread in order to prevent exposure to occupants as much as possible. Accurate UVGI luminaire emission profiles are needed to calculate the dose required for disinfection of airborne microorganisms. A radiometric measurement protocol for UVGI luminaires is a basis for this method of measurement. This guide is intended to promote uniformity and accuracy in the measurement of UVGI luminaires. Data will be exportable to any standard electronic data file formats for use in lighting software programs adapted for UVGI application.
