Gamma ray induced radiation damage in PWO and LSO/LYSO crystals


This paper compares γ-ray induced radiation damage effect in two kinds of heavy crystal scintillators: PWO and LSO/LYSO. Scintillation emission, optical transmission, light output, decay kinetics and light response uniformity were measured for PWO and LSO/LYSO crystal samples of large size before and after γ-ray irradiations. γ-ray induced phosphorescence was also measured, and the corresponding readout noise was determined.
