| 中文摘要: |
| 控制器的耐辐照性能是核环境作业机器人能否应用于高剂量率γ射线测量技术的基本指标之一,通过局部屏蔽或封装的方法可提高电子器件的耐辐射能力。论文采用MCNP5(基于蒙特卡罗方法计算中子、光子、电子输运问题的通用软件包)模拟研究了钨、铅等多种重金属及合金对γ射线的屏蔽性能,在模拟计算的基础上对屏蔽层材料及其厚度进行了优化设计。 |
| 英文摘要: |
| The radiation resistance of the sensor is one of the basic indicators of whether the nuclear environment operation robot can be applied to the high dose rate gamma-ray measurement technology. The radiation resistance of electronic devices can be improved through the method of partial shielding or packaging. The thesis uses MCNP5 simulation to study the shielding performance of various heavy metals and alloys against γ-rays. Based on the simulation calculation, the shielding layer material and its thickness are optimized design. |
