| 中文摘要: |
| 针对放射性惰性气体在“Marinelli Beaker”（简称MB）容器中，用NaI（TI）闪烁探测器测量γ射线，采用蒙特卡洛计算方法计算NaI（TI）晶体对^85Krγ射线的探测效率并与标准源实验刻度探测效率进行比较．应用Matlah软件对不同体积的MB容器的理论计算和实验刻度数据分别用最小二乘法进行拟合并比较．比较结果显示，理论计算值和实验数据在误差范围内是一致的。 |

| The efficiency of NaI(Tl)scintillation crystals detector for Marinelli Beaker with the noble gas radioactive source is calculated by Monte Carlo method and the experiment using(~(85) Kr) standard source.The comparison between the theory calculation to the Marinelli Beaker of different volume using Matlab software and the experimental calculation data is made by the least square method.The comparison result shows that the theory calculation and the experimental data are equal in deviation. |
