摘　　要：目的初步探讨^(6)LiF-^(7)LiF与CR39监测中子个人剂量方法的差别,为完善中子个人剂量监测提供参考。方法依据GBZ 128—2019对中子个人剂量进行监测,采用^(6)LiF-^(7)LiF和CR39同时监测中子个人剂量,对7家单位的26名放射工作人员进行中子个人剂量监测,同时对监测结果进行分析。结果大部分工作人员的中子个人剂量当量Hp(10)<MDL,26名人员中有6名人员2种监测方法的结果存在一定差异。结论^(6)LiF-^(7)LiF和CR39监测方法均可用于放射工作人员中子个人剂量监测,但应考虑^(6)LiF-^(7)LiF与CR39的阈能、能量响应等的区别,针对不同类别的放射工作场所人员选用合适的中子个人剂量监测方法。Objective To preliminarily compare ^(6)LiF-^(7)LiF and CR39 in individual neutron dose monitoring,and to provide a reference for improving individual neutron dose monitoring.Methods According to the GBZ 128-2019,26 radiation workers from 7 institutions received individual neutron dose monitoring with ^(6)LiF-^(7)LiF and CR39 at the same time.The monitoring results were analyzed.Results For most of the workers,the personal neutron dose equivalent Hp(10)was less than the minimum detectable level.The results with the two monitoring methods differed in 6 of 26 workers.Conclusion Both ^(6)LiF-^(7)LiF and CR39 monitoring methods can be used for individual neutron dose monitoring for radiation workers,but the difference between ^(6)LiF-^(7)LiF and CR39(in threshold energy,energy response,etc.)should be considered so that different types of radiation workers receive appropriate individual neutron dose monitoring.
