Paper Abstract

This work presents the results of an ultraviolet irradiance intercomparison concerning two quantities: ultraviolet irradiance in the range of 250 to 400 nm and effective ultraviolet irradiance, which aims to support the ultraviolet radiation metrological issues of medical equipment manufactures and occupational ultraviolet evaluation. The intercomparison participants are medical equipment company laboratory and university or independent laboratories. The intercomparison is performed in the round robin model and a 1000W seasoned filament FEL lamp attached to housing with quartz lens is used as intercomparison measurement object. The lamp ultraviolet irradiance reference measurement is made by a spectroradiometer and is performed before and after all participants’ measurements, which allows the evaluation of the irradiance drift. The normalized error is used as the intercomparison measurement agreement criterion. Results show that 16.7% of measurement is in agreement and after some measurement procedures corrections the result agreement percentage is 66.7%.
