Abstract

Radiation resistance of composite scintillators containing grains of organic or inorganic single crystals has been analysed. The analysis is based on the study of composite scintillators containing grains Gd2SiO5:Ce (GSO:Ce), Gd2Si2O7:Ce (GPS:Ce), Al2O3:Ti, Y2SiO5:Ce (YSO:Ce) or Y3Al5O12:Ce (YAG:Ce). This paper presents the results of research and suggests possible mechanisms as well as processes of radiation changes that occur in scintillators due to irradiation. It also discusses how these effects can affect the scintillation characteristics of composite scintillators exposed to radiation.
