A sensor section (2) is provided with a detection element (7) sensitive to light and radiation so that normal operation of the sensor section (2) can be confirmed. The function for confirming operation of the sensor section (2) using an optical pulse signal from a light emitting element (9) is controlled from a monitor module section (3) for connection with the sensor section (2). When the optical pulse for confirming operation of the detection element (7) is generated, output from the sensor section (2) is excluded from operation at the monitor module section (3) 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 (2) is high counting rate is provided over both the sensor section (2) and the monitor module section (3). |
