RADIATION VISUALIZATION DEVICE, RADIOACTIVE MATERIAL MONITORING METHOD AND RADIOACTIVE MATERIAL LEAKAGE DETECTION METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a radiation visualization device which allows a user to easily, intuitively and visually grasp the dose-rate distribution.SOLUTION: In a radiation visualization device comprising: a scintillation fiber which detects a radiation of an object to be measured in an environment; photoelectric multipliers 30, 30' which convert and amplify an optical signal generated by the scintillation fiber into an electric signal; signal waveform pre-processing units 50, 50' which perform signal waveform pre-processing on the electric signal from the photoelectric multipliers 30, 30' for improving temporal resolution; a multiple peak analyzer 80 which performs classification in accordance with the intensity of the signal; and a display unit 100 which visualizes an output signal from the multiple peak analyzer 80, the display unit 100 consists of a plurality of light-emission parts arranged in a first direction in parallel to the longitudinal direction of the scintillation fiber.
