摘要：
A parameter measuring detector, i.e., radiation detector (10, 42), is subjected continuously to the parameter of interest of a monitored environment (ME) and intermittently to a predetermined level of the parameter from a check source (12, 40). The output signal of the detector is separately averaged during both the time (T1) the detector is subjected to the parameter level of the monitored environment and the predetermined level of the parameter and the time (T2) it is subjected only to the parameter level of the monitored environment. The difference between the two averages represents the predetermined level of the parameter as measured by the detector. This value is compared against the actual value of the predetermined level to determine the operational integrity of the detector. This signal processing technique eliminates the need for a check source of high strength which creates a radiation hazard and which is used to monitor high radiation channels such as a post-accident monitoring channel in nuclear reactor installations.
摘要（中）：
参数测量检测器，即辐射检测器（10,42），从检查源（12,40）连续地受到监测环境（ME）的感兴趣的参数并且间歇性地受到参数的预定水平的影响。 在检测器受到监测环境的参数水平和参数的预定水平的时间（T1）和时间（T2）之间，检测器的输出信号分别进行平均，时间（T2）仅受到参数水平的影响 监控环境。 两个平均值之间的差表示由检测器测量的参数的预定水平。 将该值与预定水平的实际值进行比较，以确定检测器的操作完整性。 该信号处理技术消除了对产生辐射危害的高强度检查源的需要，并且用于监测核反应堆设备中的诸如事故后监测通道的高辐射通道。
