Title:
RADIATION DETECTION DEVICE, RADIATION DOSIMETRY PROCESSING METHOD, AND RADIATION DOSIMETRY PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2015/129069
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a radiation detection device whereby sensitivity of light detection can be increased despite using a simple photodetector having a small light receiving surface area and low sensitivity of light detection, and sensitivity of radiation detection can be increased as a result; a radiation dosimetry processing method; and a radiation dosimetry processing program. The configuration for achieving this purpose is provided with a radiation detection unit (2) for generating a radiation detection signal corresponding to the energy of incident radiation (R), a stochastic resonance unit (7) for causing a stochastic resonance effect in the radiation detection signal generated by the radiation detection unit (2) and outputting a waveform reproduction signal in which the waveform of the radiation detection signal is reproduced, and a calculation unit (8) for measuring a radiation dose on the basis of the waveform reproduction signal generated by the stochastic resonance unit (7).
