EURADOS IC2019_exteye- a self-funded intercomparison for extremity and eye lens dosemeters organised by EURADOS working group 2

The European Radiation Dosimetry Group (EURADOS) has been organising regular, self-funding, external dosimetry intercomparisons (ICs) since 2008. IC2019(exteye), for extremity and eye lens dosemeters, attracted 113 systems (68 extremity and 45 eye lens) from 60 institutes with participants from 26 countries around the world. Irradiations were carried out in accredited European irradiation facilities in terms of H-p(0.07)/or H-p(3) in the ranges: photon energy: 16-662 keV, beta mean energy 250-1000 keV, dose: 0.5 mSv to 1 Sv, maximum angle of incidence: +/- 60 degrees. This paper describes the IC2019(exteye) set-up, irradiation plan and coordination with an overview of the main conclusions. Out of the total of 113 systems, 57 reported results for photons only and 56 reported both photon and beta. In general, the participants showed very satisfactory performances with the medians of all H-p(0.07) and H-p(3) response values very close to unity.
