Abstract
The present invention relates to single, dual and multiple channel ultraviolet radiation measurement devices for obtaining a dosage level and an intensity level of an ultraviolet radiation source directed at an irradiation target. The device includes a measurement sensor having a light pathway formed between first and second ends. An internal light guide is positioned along the light pathway adjacent the first end. An external light guide chamber is formed along the light pathway adjacent the second end and extending toward the internal light guide. A light scattering member is positioned along the light pathway. An electric charge generating unit is positioned adjacent the light pathway, an electric charge storage unit is electrically connected in parallel with the electric charge generating unit, a resistive member is selectively electrically connectable in parallel with the electric charge storage unit, and an electrometric unit is electrically connected to the electric charge storage unit.
