Abstract

The EURADOS intercomparison IC2021area with its main focus on low dose measurements was carried out between May 2021 and April 2022 for passive H*(10) area dosimetry systems. Three measurement conditions were provided at locations of the Karlsruhe Institute of Technology: 3-months indoor, 3-months outdoor and 6months outdoor. The challenge for the 65 participating dosimetry systems of this intercomparison was measuring additionally irradiated low dose 137Cs gamma radiation of 150 mu Sv and 300 mu Sv. Despite the comparably high background dose values between about 200 mu Sv and 1600 mu Sv, more than 90% of the resulting response values of the irradiated dosemeters were within the recommended ISO 14146 response limits. The calculated detection limits of the participating dosimetry systems were in most cases clearly below the desired value of 150 mu Sv of this intercomparison.
