[abstract] The reading of polysulphone film (PSF), resulting from fractionated exposures to monochromatic UV radiation, was compared with the response to continuous irradiations of the same radiant exposure and wavelength. Also studied was the effect of a pre-exposure to monochromatic UV radiation on the reading resulting from a subsequent irradiation at a different wavelength. The results are used for a physical description of the detector reading resulting from given spectral radiant exposures. This allows readings of PSF after exposures to polychromatic UV radiation to be calculated. The description was tested for solar UV radiation at ground level and good agreement between experimental and calculated detector readings was achieved.
