【摘要】 核能和核科学技术的应用已给人类带来巨大的经济效益和社会效益，但是所伴随的辐射照射也可能给人类造成损害。在核工业迅速发展的年代里，人们认识到随着核工业的发展，在核设施的设计、运行和退役过程中，辐射防护最优化显得愈来愈重要了。 本文主要是针对γ射线屏蔽材料进行了优化分析与研究。建立了优化数学模型，编制了优化程序，并对三组试件分别进行了优化计算，对优化计算的结果进行了分析。设计并建立了实验系统，并利用VI(Virtual Instrument)技术编制了数据采集软件，使得所采集的数据能够实时准确的显示与保存。最后通过实验对优化计算的几组γ射线屏蔽试件的屏蔽效果进行了实验验证。通过对实验结果的分析，说明本文所采用的优化方法是正确的，实验的结果是可信的，达到了我们预期的目的。更多还原

【Abstract】 The application of nuclear energy and nuclear science and technology have already brought enormous economic benefit and social benefit to mankind, but the radiation followed may do harm to mankind. During the times that the nuclear industry develops rapidly, people realize that with the development of nuclear industry, the optimization of radiation protection seems more and more important among the design, operation and ex-service of nuclear facilities.This paper mainly analyses and studies the optimization about the shielding materials of gamma ray. The text has set up the mathematics model of optimizing, has worked out the program of optimizing, has finished the optimization calculation of the three group samples, has made the analysis for the optimization calculation results, has set up experimental system, and has utilized VI (Virtual Instrument) technology to work out data gathering software, which makes the gathered data real-time accurate when being displayed and saved. Finally, the shielding effects of the several group gamma ray shielding samples which are optimization calculated, are proved through experiments. An analysis of the experimental results shows that the optimization method adopted in this paper is correct, the results of the experiment is believable, and we achieve our anticipated purposes.更多还原
