Abstract
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
