摘　　要：设计了一种单球3个位置灵敏计数器不同分区方法,借用蒙特卡罗模拟对5个计数区的中子能量响应进行了计算,并分析5个计数区的能量响应合理性。基于能量响应假设实验,利用少道解谱UMG软件包对诸如注量和周围剂量当量的剂量学量进行计算,并对计算的结果进行了讨论。设计了一种单球3个位置灵敏计数器不同分区方法,借用蒙特卡罗模拟对5个计数区的中子能量响应进行了计算,并分析5个计数区的能量响应合理性。基于能量响应假设实验,利用少道解谱UMG软件包对诸如注量和周围剂量当量的剂量学量进行计算,并对计算的结果进行了讨论。A different dividing-region method for a sphere and three position-sensitive counters was designed. Neutron energy responses of five counter-regions were calculated by mean of Monte Carlo simulation, and reasonable energy responses for five counter-regions were analysed. Based on the test hypothesis of energy responses, the dosimetry quantities such as fluence and ambient dose equivalent were calculated using ＂few-channel＂ unfolding code, and the results calculated were discussed.
