| Abstract: | The source and characteristics of several rays which are often melting with in radioactive jobs are reviewed. It briefly introduces the kinds and shielding principal of these materials. It points out that the most applied and best means is looking for the little and light fiber with good shielding effect or the added rare-earth-alloy composite. It proposes that the research direction of present shielding materials is enhancing the shielding effect of these rare-earth elements by improving the preparation process and the etfect of rare-earth on this composite. |
