Ajoint UAB-IReS-IPNO neutron comparison exercise with nuclear track detectors

摘要

The response of PN3 and CR-39 personal dosemeters, with different configurations, developed by the IReS (Strasbourg), the IPNO (Orsay) and the UAB (Barcelona) groups, is investigated in this study. Both dosemeters were mounted on a water-filled phantom and were simultaneously exposed under different incidence angles (0 degrees, 30 degrees and 60 degrees) to the following: (i) three ISO neutron sources (Am-241-Be, bare Cf-252 and moderated Cf-252 with Cd shielding), and (ii) two realistic neutron sources (SIGMA and moderated Cf-252) at the IRSN (Cadarache) facilities. After irradiation, the plastic detectors were etched and evaluated according to local routine procedures and corrections for the effect of source-to-detector distance were taken into account. A comparison of the average background, the minimum detectable dose equivalent and the field calibration factor is performed as well. (c) 2005 Elsevier Ltd. All rights reserved.
