摘要
随着核能的开发应用,研究环境中铀、钍、钾等长寿命放射性核素的放射性水平,对保护公众安全和生态环境具有重要意义。采用中子活化分析方法,对罗布泊地区环境样品作了放射性检测。根据该样品的比活度以及该样品的元素丰度与中国大陆地壳元素丰度的比较,表明罗布泊地区的地质放射性无明显的放射性异常,并可以作为建筑材料使用,符合GB 6566-2001标准。
With the development and application of nuclear e.nergy, research radioactive levels of uranium, thorium, potassium and other long - lived radio nuclides in environment to protect public safety and the ecological environment of great significance. The radioactive levels of environmental samples in the Lop Nur region were detected by neutron activation analysis method, according to the specific activity of samples and the sample element abundances in comparison with the Chinese continental crust element abundances. So it brought the resuh that the Lop radiological abnormality. According to GB 6566 - materials. Nur region, geological radioactive - free obvious 2001 standards, that can be used as construction
