Abstract: EURADOS has carried out a number of different intercomparison exercises for personal dosemeters in the past that qualify as proficiency tests for different dosimetry systems and radiation types including one previous neutron personal dosemeter intercomparison (IC2012n). Neutron intercomparisons are especially complicated to design because of the limited availability of reference fields and the costs associated with the exposures. IC2017n was the second EURADOS organized intercomparison exercise for neutron personal dosemeters. It was an important...
