X射线屏蔽材料设计与制备的研究进展

Research progress of design and production of X-ray shielding materials

介绍X射线的特点及其屏蔽机制,详述X射线屏蔽材料的研究进展,提出材料的复合制备技术、梯度化设计以及遗传算法优化设计以制备轻质、高效、耐久的新型屏蔽材料,同时应发挥稀土元素和纳米材料的优势来增强屏蔽材料的综合性能。

The characteristics and shielding mechanism of X-ray were introduced. The state-of-the-art of X-ray shielding materials was also reviewed in detail. Composite teehnology, gradient method and optimal design were put forward to fabricate lightweight and efficient radiation shielding materials. It was also pointed out that rare earth elements and nano-materials, as novel radiation shielding materials, should be used to enhance the overall performance of shielding material.
