Meanwhile,using 241Am,57Co Gamma-ray to estimate its characteristic of nuclear ratiation detectors. After measurement,we find that the leakage of surface barrier t- ype is 1nA,but 10nA for photoconductor type when the reverse bi- as is 100V.However the photoconductor type has a good absorptio- n ability with high energy Gamma- ray,and there was no phenomen- on of polarization occured.After annealing at 100℃ 2 hour,it has an energy resolution of 4.37KeV for 57Co Gamma-ray.
