摘要
核辐射探测器阵列的探测下限是判断其是否符合探测要求的重要技术指标。从定性的角度易知,由于核材料移动时比静止时的探测下限低而更难以探测。文章通过建立蒙特卡罗模型并应用通用软件MCNP程序分析计算核材料的移动对核辐射探测器阵列探测下限的影响。
The minimum detectable limit of the nuclear radiation detector array is an important technic criteria to judge whether the detector satisfies the detecting requirements or not. The detection of moving nuclear material is more difficult than that of static one （namely, the minimum detectable limit of moving nuclear material is lower than that of static one）. This study adopts the Monte-Carlo general software-MCNP to compute and analyze the effect of movement of the nuclear matter on the minimum detectable limit of the nuclear radiation detector array.
