gamma-RAY DETECTION CAMERA DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an inexpensiveγ-ray detection camera device with high position resolution enabling a user to detectγ-ray with high precision. SOLUTION: Theγ-ray detection camera device is to detectγ-rays 15a and 15b generated by a radiation source 14 using scintillation detectors 1 which are provided to sandwich the radiation source 14 and formed by a plurality of NaI scintillator elements 2 aligned, wherein the thickness of the NaI scintillator element 2 in the aligned direction 13 is reduced so that each of the NaI scintillator elements 2 can detect theγ-rays 15a and 15b generated by the radiation source 14 in the aligned direction 13.
