Performance of a radiophotoluminescence (RPL) system in environmental and area monitoring

Abstract The objective of this work was to perform an extensive side-by-side comparison between a radiophotoluminescence (RPL) dosimetry system and thermoluminescent dosimeters (TLDs) or EDIS-1™ Environmental Direct Ion Storage Dosimeters during environmental and area monitoring. The measurement locations include points around and within the perimeter of the Paul Scherrer Institute (PSI) and nearby facilities. These data are complemented by a study on the RPL detection limit, uncertainty and dose linearity, as well as two intercomparisons of environmental dosimeters, a Swiss intercomparison organized by PSI and an international intercomparison organized by the German National Metrology Institute (Physikalisch-Technische Bundesanstalt, PTB, Germany). The laboratory irradiations show that the detection limit of the RPL dosimeters is
