Measurements of neutron ambient dose equivalent rates are challenging because there are no perfect instruments that cover the entire 9 orders of magnitude neutron energy range (thermal to 20 MeV). Hence quantifying performance requirements with the international standard IEC 61005 for neutron ambient dose equivalent rate meters presents unique challenges. This paper discusses the requirements of this standard, which have been refined and improved over the last 20 years. Examples of type testing results for the constancy of ambient dose rate response, variation of the response due to neutron energy, response time, and various environmental disturbances are examined. IEC 61005 provides manufacturers with internationally acceptable requirements and provides consistent test methods for compliance with stated performance requirements.

制定和使用中子环境剂量当量率计的国际标准

中子环境剂量当量率的测量具有挑战性，因为没有完美的仪器可以覆盖整个 9 个数量级的中子能量范围（热到 20 MeV）。因此，根据国际标准 IEC 61005 量化中子环境剂量当量率计的性能要求提出了独特的挑战。本文讨论了该标准的要求，这些要求在过去 20 年中得到了细化和改进。检查了环境剂量率响应的稳定性、中子能量引起的响应变化、响应时间和各种环境干扰的型式测试结果示例。 IEC 61005 为制造商提供了国际上可接受的要求，并提供了一致的测试方法以符合规定的性能要求。
