摘　　要：实验尝试采用治疗水平60Co参考辐射的剂量当量率覆盖高剂量率区,采用防护水平137Cs参考辐射覆盖中低剂量率区,实验测量并计算得到FHZ612-10型号仪器对60Co参考辐射响应转换为137Cs参考辐射响应的修正因子为(1.011,-68.733),实现了对应急防护用γ辐射剂量当量率仪的宽量程校准因子测量方法的探索。In this experiment, the dose equivalent rate of 60 Co reference radiation at the therapeutic level was used to cover the high dose rate range, and 137 Cs reference radiation at the protective level was used to cover the medium and low dose rate range. The correction factor of FHZ612-10,which converts 60 Co reference radiation response to 137 Cs reference radiation response, is (1.011,-68.733) derived from measurement and calculation.Measuring method of the wide range calibration factor of gamma radiation dose equivalent rate instrument for emergency protection has been explored.
