The American National Standard ANSI N13.11-1983 is used to test the accuracy (bias plus precision) of dosimetry processors as part of the dosimetry accreditation program of the National Voluntary Laboratory Accreditation Program (NVLAP). Section 3.8 of the ANSI N13.11-1983 standard requires that a study of the angular response of a dosimeter be carried out once, although no pass/fail criterion is given for angular response. The NVLAP accreditation program excluded Section 3.8, and thus no angular response data have been generated in an organized fashion. The objective of this project is to examine the feasibility of two alternative methods to test the angular response of personnel dosimeters. The first alternative involves static irradiations with the dosimeters at fixed angles to a radiation source. The second alternative involves dynamic irradiations with the dosimeters mounted on a rotating phantom. A Panasonic UD-802 personnel dosimetry system** was used to generate data to examine both alternatives. The results lead to two major conclusions. Firstly, Section 3.8 of the ANSI N13.11-1983 standard should be amended to require a pass/fail test for angular response. Secondly, a comparison between angular response data generated with a fixed or a rotating phantom shows that the rotating phantom is the more cost-effective method.
美国国家标准ANSI N13.11 - 1983用于测试剂量测定处理器的准确性（偏差加精密度），作为国家自愿实验室认可计划（NVLAP）剂量测定认可计划的一部分。ANSI N13.11 - 1983标准的第3.8节要求对剂量计的角响应进行一次研究，尽管未给出角响应的通过/失败标准。NVLAP认可计划排除了第3.8节，因此没有以有组织的方式生成角响应数据。本项目的目的是研究两种测试个人剂量计角响应的替代方法的可行性。第一种替代方法是将剂量计以固定角度对辐射源进行静态照射。第二种替代方法是将剂量计安装在旋转体模上进行动态照射。使用松下UD - 802个人剂量测定系统**生成数据以研究这两种替代方法。结果得出两个主要结论。首先，应修订ANSI N13.11 - 1983标准的第3.8节，要求对角响应进行通过/失败测试。其次，对使用固定或旋转体模生成的角响应数据进行比较表明，旋转体模是更具成本效益的方法。
