To provide an opportunity for dosimetrists to test and calibrate their neutron personnel monitoring systems, the staff of the Dosimetry Applications Research (DOSAR) Facility at the Oak Ridge National Laboratory (ORNL) has conducted personnel dosimetry intercomparison studies (PDIS) periodically since 1974. During these studies, personnel dosimeters are mailed to ORNL, exposed to low-level (less than 15 mSv) neutron dose equivalents in a variety of mixed-radiation fields, and then returned to the participants for evaluation. These intercomparisons have provided more data on neutron dosimeter performance than any other periodic test program conducted to date. This report presents a summary and analysis of about 3450 neutron dose equivalent measurements reported for PDIS 7 through 12 (1981-1986) with emphasis on low dose equivalent sensitivity, accuracy and precision, and performance relative to accreditation standards for the basic types of personnel dosimetry systems. Relationships of the PDIS results to occupational neutron monitoring, accreditation testing, and methods to improve personnel neutron dosimetry performance are also discussed.
为了给剂量测定人员提供测试和校准其中子个人剂量监测系统的机会，自1974年以来，橡树岭国家实验室（ORNL）剂量测定应用研究（DOSAR）设施的工作人员定期开展个人剂量测定比对研究（PDIS）。在这些研究中，个人剂量计被邮寄到ORNL，在各种混合辐射场中接受低水平（小于15毫希沃特）的中子剂量当量照射，然后再返还给参与者进行评估。与迄今开展的任何其他定期测试项目相比，这些比对提供了关于中子剂量计性能的更多数据。本报告对第7至12次个人剂量测定比对研究（PDIS，1981 - 1986年）报告的约3450次中子剂量当量测量结果进行了总结和分析，重点关注低剂量当量灵敏度、准确性和精密度，以及相对于基本类型个人剂量测定系统认可标准的性能。还讨论了个人剂量测定比对研究结果与职业中子监测、认可测试以及提高个人中子剂量测定性能方法之间的关系。
