内蒙古境内部分地表水放射性水平研究

本文根据国家水中放射性元素检测方法和相关的技术规范，监测了内蒙古自治区境内部分地表水中的铀（U）、钍（Th）、镭（Ra-226）、总α和总β的剂量，并与内蒙古自治区本底数据和文献监测数据比较。结果表明，内蒙古境内部分地表水中放射性核素均在内蒙古自治区环境本底调查范围之内，与文献监测值比较基本一致，并低于国家限制浓度，生产生活使用该处地表水是安全的。

Investigation of Radioactivity Level in Inner Mongolia of Part of the Surface Water

Radioactive elements in this paper, according to the national water detection method and the relevant technical specifications, monitoring of the Inner Mongolia autonomous region in part of the surface water in uranium （ U ） and thorium （ Th ） , radium （ Ra - 226 ） , the total dose of alpha and beta, with Inner Mongolia autonomous region and background monitoring data and literature data comparison. The results show that the radioactive nuclides are part of the surface water within the boundaries of Inner Mongolia in the range of the Inner Mon- golia autonomous region environment background survey, compared with the monitoring value of literature, and below the national limit con- centration, production and living surface water is safe to use here.
