The European Radiation Dosimetry Group has carried out several different types of intercomparison (IC) exercises in the past that qualify as proficiency tests for different dosimetry systems and types of radiation. The first neutron dosemeter IC was held in 2012 (IC2012n) and was followed by a second in 2017/2018 (IC2017n). In sum, 31 Individual Monitoring Services (IMSs) entered 34 dosimetry systems in IC2012n, and 32 IMSs entered 33 dosimetry systems for IC2017n. Such exercises provided a rare opportunity to see how neutron dosemeters perform. For the IC2012n exercise, there were no applicable performance standards for neutron personal dosemeters. ISO/TC85/SC2 updated the ISO Standard 14146 in 2018 (ISO 14146:2018. Radiation protection-Criteria and performance limits for the periodic evaluation of dosimetry services) to include neutron dosimetry. It was thus possible to analyse the IC2017n exercise in accordance with the requirements given by this new standard. It is now of interest to reanalyse the results of IC2012n to quantify any modifications to the conclusions.
欧洲辐射剂量学组过去进行了多种不同类型的比对（IC）实验，这些实验可作为不同剂量测量系统和类型辐射的熟练测试。第一次中子剂量计 IC 于 2012 年进行（IC2012n），随后于 2017/2018 年进行了第二次（IC2017n）。总的来说，31 个个人剂量监测服务机构（IMS）在 IC2012n 中输入了 34 个剂量测量系统，32 个 IMS 在 IC2017n 中输入了 33 个剂量测量系统。此类实验提供了难得的机会，可以观察中子剂量计的性能。对于 IC2012n 实验，没有适用于中子个人剂量计的性能标准。国际标准化组织/技术委员会 85/标准分委员会 2 于 2018 年更新了 ISO 标准 14146（ISO 14146：2018. 辐射防护-剂量测量服务定期评估的标准和性能限值），将中子剂量测量纳入其中。因此，有可能根据新标准的要求对 IC2017n 实验进行分析。现在，重新分析 IC2012n 的结果以量化对结论的任何修改很有意义。
