Title:
RADIATION MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/043076
Kind Code:
A1
Abstract:
Provided is a radiation measuring device comprising: a gas scintillator; at least two optical sensors that generate pulse signals in response to the reception of scintillation light; and a detection unit that detects the generation of radiation on the basis of the pulse signals generated by each of the optical sensors, wherein the detection unit excludes a calculation result less than a prescribed threshold, from calculation results for the pulse signals generated by the optical sensors during a prescribed time period in a state in which an object to be measured for the radiation is present in the gas scintillator, and the detection unit thereby detects the radiation generated by the object to be measured, and the threshold value is determined through calculations for the pulse signals generated by the optical sensors during a prescribed time period in a state in which the object to be measured for the radiation is not present in the gas scintillator.
