Irradiation damage,and its recovery in the optical transmission,the light-exited fluorescence spectra and the thermo-luminescence of BaF_2 scintillators by using expeure tO α ̄(60)γ- ray irradiation were investigated. The doses of γ- ray are 1. 39 × 10 ̄7 rad and 7.8×10 ̄6 rad.The investigation indicate that irradiation damage characteristics of scintillator materials have relation to kind and quantity of impurity in raw materials.
