稀土元素常与铀钍等放射性核素共生在一起,其产品都伴有放射性,稀土矿中γ射线最强,是一种不可忽视的危害因素。我市某稀土矿海拔63m,是以霓辉石英正长岩为主体的矿,山上居民约8000人,多在9代以上。为探讨开采稀土元素对周围地区所造成的放射性影响,对该矿外环境进行了天然辐γ射水平的监
Rare earth elements and uranium thorium and other radionuclides often symbiotic together, their products are accompanied by radioactive, rare earth mine gamma rays strongest, is a can not be ignored as a hazardous factor. A rare earth mine in our city is 63m above sea level. It is based on Ni-quartz quartz syenite. There are about 8000 inhabitants in the mountain, more than 9 generations. In order to explore the radioactive effects of rare earth elements mining on the surrounding area, the natural radiation level of natural γ radiation
