摘要： PROBLEM TO BE SOLVED: To provide a scintillation detector that will not have average DC level from varying, even with respect to significant changes in the luminance of incident radiation.
SOLUTION: A negative bias voltage is applied to a photocathode K from a bias power supply terminal 6, in order to bring the anode A of a photomultiplier tube 2 to be at the zero potential. Rather than DC coupling, AC coupling using a capacitor is configured in each of signal paths between the output of the photomultiplier tube 2 and the input of a DC-type waveform shaping amplifier 3, and between an output of the DC-type waveform shaping amplifier 3 and an output terminal 5 of the scintillation detector.

摘要： PROBLEM TO BE SOLVED: To provide a simplified body surface contamination monitor of a separation system which can be easily transported and installed for detecting and measuring radioactive contamination of body surfaces of persons to be measured in nuclear facilities, etc. SOLUTION: In this body surface contamination monitor, two detectors 3 and 4 having detection faces 5 and 6 of a size capable of covering the body of the person to be measured from one face are set to hold the person between the detection faces 5 and 6 to measure radioactive contamination of the body surface of the person. Each of the detectors 3 and 4 is formed to be separated at a middle part in a heightwise direction. The detectors are carried to a measurement spot in a state while separated, and assembled and set to be used there.
