摘要：

An efficiency transfer code based on disk source is established to calibrate efficiency of 133Xe gas sample. 133Ba disk sources were used to simulate the detection efficiency of 133Xe cylindrical volume source. Relationships were established based on peak efficiency ratio between 137Cs and 133Ba. Cascade summing effects in close geometry gamma-ray spectrum of 133Ba was solved based on the ratios calculated by LabSOCS simulation and the experiment data of long and short distances. Finally, the efficiency transfer code is used to calibrate 133Xe gas sample's efficiency. The detection efficiencies using the efficiency transfer code are consistent with the results of disk source simulation with discrepancy about ±1%.
