Abstract
Provided is a measurement unit and measurement method for reducing attenuation due to optical fiber length and SN degradation due to background in a dosage rate monitor that uses optical fiber. This system comprises: a radiation detector for detecting radiation dosage; a light source for irradiating stimulating light on the radiation detector; a photodetector for detecting light generated by the radiation detector; an optical fiber for connecting the photodetector and the radiation detector and light source, and transmitting light from the light source and light from the radiation detector; a measurement unit for counting the pulses outputted from the photodetector; and an analysis unit for extracting the luminous energy originating from the radiation detector, from time information, wave height information, and the count value, which are measurement results obtained by the measurement unit, and converting the luminous energy to a dosage and dosage rate.
