Design of an Image Acquisition System for Non-Destructive Testing Using High Energy Radiation; 고에너지 방사선을 사용한 비파괴검사의 영상획득 시스템 설계

초록

In non-destructive testing using high-energy radiation, the detection of cracks varies depending on the performance of the image acquisition system. Since high energy is used, the penetration is strong, so the degree measured by the detector varies, and the design of the image acquisition system is required. In general, a scintillator with excellent density is used to detect high-energy radiation, and detector using a GOS is mainly used. Existing non-destructive testing detectors on the market use a GOS with a thickness of about 1 mm, and a photodiode is used as the light sensor. A GOS with a low thickness is not enough to sufciently detect high-energy radiation. In this study, a detector with excellent density and diferent thicknesses and types of scintillators was designed to apply the image acquisition system. The performance of the designed system was evaluated through a comparative evaluation with the detector used in the past. As a result, it was confrmed that the size of the measurable cracks varied by changing the thickness of the scintillator used. The possibility of designing an excellent image acquisition system was confrmed by applying various types and thicknesses of scintillators in the detection system. © 2025 Korean Physical Society.
