Abstract

In 2008, EURADOS (the European Radiation Dosimetry Group) started to organise a self-sustained programme of regular intercomparisons with the aims of encouraging and facilitating the participation of individual monitoring services (IMS) in intercomparisons. To date, three intercomparisons for whole body dosemeters (IC2008, IC2010 and IC2012) and one for extremity dosemeters (IC2009) have been carried out. This paper presents the recent results of the 2012 intercomparison for whole body dosemeters. At the 2012 intercomparisons 75 institutes with 87 dosimetry systems (most passive) participated from 28 European and 2 non-European countries. For the irradiations a number of different reference photon radiation qualities (x-ray and nuclide sources) were used. The results show that 90% of all systems fulfil the general performance criteria from ISO 14146. The paper gives a comprehensive overview on the performance of various European dosimetry services and the influence of the dosemeter type and detector material on the resulting response values.
