Analysis of EURADOS Intercomparison IC2023calib results: H∗(10) irradiation of passive area dosemeters

The EURADOS calibration inter-laboratory exercise called IC2023calib was carried over the year 2023 with the participation of 24 calibration laboratories from 17 different countries. A total of 614 passive area dosemeters from the dosemeter providing laboratory (IRSN, France) were irradiated by the participants in terms of ambient dose equivalent H∗(10) or used as background dosemeters. The irradiation laboratories could choose to participate with one, two, three or four of the proposed standard radiation qualities (N-30, N-150, S-Cs, S-Co). The aim of this article is to analyse the results of this comparison exercise. Mean relative deviation to the reference laboratory (PTB, Germany) was used to evaluate their performance. Participants’ results were satisfactory is most cases. The exercise also provided information on the current calibration methodologies throughout Europe.
