摘要
介绍了天然本底辐射的组成和世界高本底辐射区分布,并以理论和实例说明射线对人体 的影响,最后介绍天然辐射剂量测定、调查方法。
Not only introduces the compositions of nature background radiation and the distributions of high background radiation areas in the world, but also illustrates with theories and concrete examples that the rays have influences upon the human body, and finally, presents methods to measure and investigate the nature radiation dose.
