Abstract：
The resistance to neutron irradiation of LaBr₃ scintillator was studied in this work. The change of background counting rate, light output and energy resolution of the LaBr₃ scintillator were analyzed to determine whether the scintillator was damaged under different neutron flux rates induced by ²⁴¹Am-Be, D-T neutron generator, and reactor neutron source. The results show that the neutron radiation damage in LaBr₃ scintillator is mainly affected by neutron flux rate. Under low flux rate, the properties of the scintillator were hardly changing, while under high flux rate, there is obvious deterioration in the background spectra and in the energy resolution because of the neutron activation. After a period, the neutron radiation damage will spontaneously recover.
