  • Patent number: 8637827
    Abstract: A sensor section is provided with a detection element sensitive to light and radiation so that normal operation of the sensor section can be confirmed. The function for confirming operation of the sensor section using an optical pulse signal from a light emitting element is controlled from a monitor module section for connection with the sensor section. When the optical pulse for confirming operation of the detection element is generated, output from the sensor section is excluded from operation at the monitor module section so that confirmation of operation by an optical pulse is not affected. Furthermore, a configuration for stopping the sensor operation confirmation function when the output from the sensor section is high counting rate is provided over both the sensor section and the monitor module section.
