IEC 61031:2020适用于在正常运行和预期运行事件期间监测核设施内局部伽马辐射剂量率的已安装设备的设计、位置和应用。目前IEC 60951-1和IEC 60951-3涉及的事故条件的高范围区域伽马辐射剂量率监测设备不在本文件的范围内。本文件不适用于中子剂量率的测量。如果中子剂量率对人员的总剂量当量有很大贡献，则可能需要额外的中子监测设备，具体取决于工厂设计。 本文件为在正常运行条件和预期运行事件下连续监测核设施局部伽马辐射剂量率的已安装设备的设计原则、位置、应用、校准、操作和测试提供了指南。这些仪器通常被称为区域辐射监测器。便携式仪器也用于此目的，但不在本文档范围内。

IEC 61031:2020 applies to the design, location and application of installed equipment for monitoring local gamma radiation dose rates within nuclear facilities during normal operation and anticipated operational occurrences. High range area gamma radiation dose rate monitoring equipment for accident conditions currently addressed by IEC 60951-1 and IEC 60951-3 is not within the scope of this document. This document does not apply to the measurement of neutron dose rate. Additional equipment for neutron monitoring may be required, depending on the plant design, if the neutron dose rate makes a substantial contribution to the total dose equivalent to personnel.
This document provides guidelines for the design principles, the location, the application, the calibration, the operation, and the testing of installed equipment for continuously monitoring local gamma radiation dose rates in nuclear facilities under normal operation conditions and anticipated operational occurrences. These instruments are normally referred to as area radiation monitors. Portable instruments are also used for this purpose but are not covered by this document.
