Abstract

An instrument is described that measures irradiance and the angular distribution of the intensity of ultraviolet radiation sources inside phototherapy cabinets. Failed lamps and lamps with higher or lower outputs are readily identified. The measurements are controlled from outside the cabinet, thus reducing the risk to staff from exposure to ultraviolet radiation.
