摘要
采用蒙特卡罗程序MCNP模拟了实验室HPGeγ谱仪外层屏蔽物对本底γ射线的屏蔽计算,了解物质对γ射线的屏蔽效果,并在实验的基础上给出了模拟的基本数据。然后通过HPGeγ谱仪的实测谱与模拟结果相比较,以验证模拟计算的正确性。
In the article, we simulated the shielding of background γray based on MCNP programme in order to know the shielding effects of the materials surrounding the HPGe detector and provided the parameters based on experiments. At last, we compared the result of simulation with that of experiment to verify whether the result of simulation is right.
