The UV dose refers to the physical quantity radiant exposure, which is defined for a plane area element with fixed orientation in space and thus radiation intercepting this area element is weighted with the cosine of the angle of incidence. For this reason, a UV dosemeter also has to weight incoming radiation with the cosine of the angle of incidence. The angular dependence of the efficiency of polysulphone film was determined experimentally. The investigations were carried out with monochromatic UV radiation at three different wavelengths as well as with polychromatic radiation. Angles were varied between normal incidence and 70°. Within this range, the angular dependence of the efficiency of polysulphone film follows the cosine function. This behaviour is independent of the wavelength and applies for monochromatic as well as for polychromatic radiation. These experimental results are corroborated by earlier theoretical considerations.
