摘　　要：随着核工业、核电及中子辐射治疗的发展,对职业工作者的中子个人剂量监测显得越为重要。利用MCNP-3B蒙特卡罗程序对反照率热释光中子个人剂量计进行了设计计算,给出了光子及中子注量响应,并对中子的场所修正因子确定方法进行介绍。模拟计算表明,对光子和中子而言,适用的能量范围分别为33 keV～1.5 MeV和热中子-10 MeV,分别对应的能量响应偏差均小于30%和60%。The monitor of neutron personal dose to professional worker become more and more important with the development of nuclear industry,nuclear plant and nuclear radiation cure.The design and calculation of TLD-albedo personal dosimeter were taken by using MCNP-3B Monte Carlo code.After the present of neutron and photon fluence response,the method to determine the field correction factor was introduced.The calculated results showed that TLD-albedo personal dosimeter could work well for photon with energy： from 33 keV to 1.5 MeV and for neutron with energy from thermo-neutron to 10 MeV,and corresponding energy response deviation could be less than 30% and 60% respectively.
