Abstract

Abstract:

Scintillation crystals are a class of crystalline materials that can generate visible light under the action of high-energy particles or high-energy radiation， and convert the kinetic energy of high-energy particles into light energy. This study takes two types of scintillation crystals， Ce∶LuYSiO₅ （Ce∶LYSO） and Ce∶Y₃Al₅O₁₂ （Ce∶YAG）， as the research objects and conducts systematic performance tests. For the light yield， the measurement was conducted using the ORTEC4518 scintillation detector system， and the results showed that the light yield of the Ce∶YAG crystal is 52300 ph/MeV， while that of Ce∶LYSO crystal is 27700 ph/MeV. In terms of detection limits， the measurement was performed using the Lanjing Technology LJ-WF300 low-background multi-channel γ-spectrometer. The results showed that the minimum detectable X-ray dose rate of the Ce∶LYSO crystal is 92 μGy/s， and that of the Ce∶YAG crystal is 95 μGy/s. This characteristic indicates that both crystals exhibit high sensitivity to low-dose X-rays， making them suitable for low-dose radiation detection scenarios. The above data provides an important basis for the application of Ce∶LYSO and Ce∶YAG scintillation crystals in the radiation imaging field.
