EURADOS INTERCOMPARISONS IN EXTERNAL RADIATION DOSIMETRY: SIMILARITIES AND DIFFERENCES AMONG EXERCISES FOR WHOLE-BODY PHOTON, WHOLE-BODY NEUTRON, EXTREMITY, EYE-LENS AND PASSIVE AREA DOSEMETERS.

The European Radiation Dosimetry Group (EURADOS) has been organising dosimetry intercomparisons for many years in response to an identified requirement from individual monitoring services (IMS) for independent performance tests for dosimetry systems. The participation in intercomparisons gives IMS the opportunity to show compliance with their own quality management system, compare results with other participants and develop plans for improving their dosimetry systems. In response to growing demand, EURADOS has increased the number of intercomparisons for external radiation dosimetry.

A co-ordinated network for radiation dosimetry (CONRAD): an overview.

The European Radiation Dosimetry Group (EURADOS) carried out a co-ordinated action, supported within the 6th Framework Programme of the European Commission entitled 'A Co-ordinated Network for Radiation Dosimetry (CONRAD)'. The project, executed from January 2005 to March 2008, yielded a large number of scientific results in different areas of dosimetry. This paper describes the objectives and general aspects of the project while the results are given in several contributions in this volume.
