There exist a variety of possible devices and methods for measurement of personal UV exposure. Often the study design already determines the measuring devices that can be used. Because of technical differences of applied dosimeters and differences with regard to modes of operation studies with the aim to quantify peronal solar UV exposure are often hardly to compare with regard to the measurement results and setup. In order to work out calibration factors for different types of commonly used dosimeter types to quantify UV irradiation three systems were selected for our intercalibration measurements: Polysulphone film (PSF), biological and electronic dosimeter. The selected systems differ in measurement principle and sensitivity, measurement accuracy and susceptibility to inaccuracies. Furthermore in a usecase the relationship between steady-state and simultaneous personal measurements of solar UV irradiation has been studied. While a calibration factor between PSF and electronic dosimeters could be derived for direct irradiation of the dosimeters, this was not the case for larger angles of incidence of solar radiation with increasing fraction of diffuse irradiation. For biological dosimeters, no intercalibration factor could be found with respect to PSF and electronic dosimeters. Dosimeters of different types can be compared with each other to a limited extent. Accordingly, the dosimeter should carefully be chosen after checking the specific needs of the intended use.
