标准摘要
[中文适用范围]： 有关核电厂规定工艺流中放射性物质水平的信息对于评估核电厂性能@以在早期阶段提供有关可能的放射性释放的信息@并使核电厂运营商能够采取行动控制这些释放是必要的。本国际标准提供了设备的设计、选择、测试、校准和功能位置的标准，用于在正常操作条件和预期操作情况下监测工厂工艺流中的放射性物质。 IEC 60768 仅适用于连续在线测量@，即探测器通过放置在过程流中（即浸入）或邻近过程流（即直接通过管道或管道观察）来测量放射性。坦克）。它不适用于探测器在某些远程位置（采样组件）@测量流的代表性比例的监测器，这些监测器在 IEC 60861 的范围内。IEC 60768 仅适用于正常和事故条件下的监测器。用于事故和事故后状况的过程流辐射监测设备属于 IEC 60951-4 的范围。 [外文原描述]： IEC 60768:2009 provides criteria for the design, selection, testing, calibration and functional location of equipment for the monitoring of radioactive substances within plant-process streams during normal operation conditions and anticipated operational occurrences. Is only applicable to continuous in-line or on-line measurement. This new edition includes the following significant technical changes with respect to the previous edition: - it clarifies the definitions; - up-dates the reference to new standards published since the first issue; - updates the units of radiation. This publication is to be read in conjunction with IEC 60951-1:2009 , IEC 60951-2:2009 , IEC 60951-3:2009 and IEC 60951-4:2009 .
