The Sensitivity comparison of some common scintillation detectors between the magnitude before and after γ irradiation with 60 Co source

In the study of scintillator irradiation resistibility,by the sensitivity comparison between the magnitude before and after γ irradiation,we can make sure if the scintillator detector can work normally after the large exposure dose.Base on the experiment using three-channels pulse λ source and DPF pulse neutron source,this paper gives the relative sensitivity of some common scintillation detector on condition of pulse neutron and pulse X-ray beam.The scintillator contains inorganic crystals as CeF3,NaI(Tl),BaF2and organic plastic scintillator such as ST-401,ST-1422 and NE111.
