摘　　要：目的　介绍一种新的个人中子剂量计的原理、结构及剂量测量特性。方法　结合有关文献报道 ,对剂量计配用6LiF(Mg ,Cu ,P)和7LiF(Mg ,Cu ,P)探测器测量2 4 1Am -Be源中子和γ射线的实验数据进行评价。结果　测量数据显示了良好的线性和重复性 ,测量中子的灵敏度是测量60 Coγ射线的 0 72 ,结果有可比性。结论　本剂量计满足在能量 4 4MeV以内的n或n -γ辐射场的人员监测要求。Objective To intruduce the principle,structure and character of a new personal neutron dosimeter.Methods In combination with relative documents,the dosimeter datum measured on neutron and γ rays emitted by 241 Am-Be source,when 6LiF(Mg,Cu,P)and 7LiF(Mg,Cu,P)are disposed,are evaluated.Results Its measurement results showed good linear relationship and can be repeated.The sensitivity of neutron detection is 0.72 times of 60 Co γ rays and this result is similar to that to be reported previously.Conclusion The measurement results of this dosimeter has been satisfied with the requirement of personel dose measurement in n or n-γ radiation field under 4.4 MeV energy.
