希土元素的化学性质很活泼,几乎能与所有元素起作用,具有很多优异的性能,为工业所普遍使用,故有“工业维生素”之称。由于希土元素和放射性有一定的关系,因而在工业生产过程中,要注意放射性的卫生防护。这里特谈谈希土和希土合金的放射性卫生防护的知识。
The chemical properties of rare earth elements are very lively and can work with almost all elements. They have many excellent properties and are commonly used in the industry. Therefore, there are “industrial vitamins”. Due to the relationship between the relic elements and radioactivity, it is necessary to pay attention to radioactive health protection during industrial production. Here to talk about rare earth and rare earth alloy radioactive health protection knowledge.
