辐射防护屏蔽箱的设计
|
摘要
随着核能和核科学技术的广泛应用,辐射防护越来越受到重视。如何平衡核科学技术给人类带来的效益和降低工作人员及公众受到的辐射,成为越来越多人研究的课题。国家对放置密封源的源容器作了规定,要使其周围的辐射水平低于国家规定值。辐射防护屏蔽箱是源容器的一种,盖子与箱体采用迷宫接口,能有效防止射线外漏,屏蔽层采用镶嵌方式嵌套在内壳与骨架之间,屏蔽性能可靠。
With the wide application of nuclear energy and nuclear science and technology, radiation protection has been paid more and more attention, how to balance the radiation of nuclear science and technology brings about the benefits and the staff and the public was low, people became more and more research topics. The state sets the source containers for sealing sources, so that the radiation levels around them are below the national standard. The radiation shielding box is one of the source containers, and the cover and the box body adopt a labyrinth interface to effectively prevent the ray from leaking. The shielding layer is nested between the inner shell and the frame by inlaying mode, and the shielding is reliable.
