结合直读式个人中子剂量计的发展动态,在参考比较的基础上,提出了快中子剂量计和热中子剂量计转换屏设计方案。前者为一层聚乙烯膜,后者为~6LiF膜并罩以开孔的(靠体模一侧中心处)的Cd套。根据中子与转换屏相互作用的特点,利用蒙特卡罗方法(随机抽样)编制了不同转换屏中子剂量能量响应和角响应的计算程序。计算结果表明,对于快中子剂量计,影响因素主要是聚乙
Combined with the development trend of direct reading personal neutron dosimeter, the design scheme of fast neutron dosimeter and thermal neutron dosimeter conversion screen is put forward on the basis of comparison. The former is a polyethylene film, which is ~ 6LiF film and covered with a perforated (by the center of the body mold side) of the Cd sets. According to the characteristics of the interaction between the neutron and the conversion screen, a Monte Carlo method (random sampling) was used to calculate the energy response and the angular response of the neutron dose conversion screen. The calculation results show that for fast neutron dosimeters, the main influencing factor is Polyethylene
