摘要: 运用MCNP5程序，建立了基于MIRD数字体模的肺部γ内污染模型以及NaI(Tl)探测器模型，模拟计算了NaI(Tl)探测器对基于MIRD数字体模的肺部γ内污染的探测效率，获得了在多种空间位置上对沉积在肺部的9 种能量射线的探测效率。模拟结果表明，在不同位置的探测效率并不完全符合人体肺部的解剖学结构，在右下肺位置可获得最高的探测效率，左下肺次之，左上肺最低。在探测器位置固定的情况下，探测效率随能量的增加，有先增高后降低的现象。In order to obtain detection efficiencies of nine kinds of gamma rays emitted by isotopes deposited in lungs at various measurement geometry, Monte Carlo N-Particle Transport Code 5 (MCNP5) has been employed to for calculation. The results show that the detection efficiency in different locations of lung is not completely accord with human body’s anatomy structure. The efficiency decreases gradually from lower-right lung, to lowerleft lung, and then to upper-left lung. When the location of detector is fixed, with the increase of energy, the
detection efficiency rises up firstly and then falls down.
