Investigation on Natural Radioactive Nuclide Uranium Concentration of Water Specimen from Wangyu River by Laser Microanalysis Apparatus

In this paper, an apparatus and method which uses laser microanalysis apparatus (LMA) to analyze trace uranium of water was introduced. By this apparatus, the natural radioactive nuclide uranium consistency of water specimen from Wangyu River is investigated. The results show that natural radioactive uranium consistency of Wangyu River increases when the water flows through the drainage of uranium mine. According to the published research result, the uranium consistency of Wangyu River has increasing trend in recent years.
