摘要
文章报道了2005年度分平水期和枯水期对云南省九大高原湖泊水体放射性状况进行的调查研究结果。本次行动初步调查清楚了2005年九湖核素浓度(U、Th、^(226)Ra、^(40)K)总α和总β值的区域最大值。调查结果表明,这九大高原湖泊水体的放射性核素浓度基本属正常本底水平,没有受到人工放射性的污染。
Radioactivity levels of nine plateau lakes in Yunnan Province were studied with a survey conducted in middle flow period and low flow period of 2005 to investigate the maximum regional radioactivity value including U,Th,_(226)Ra,_(40)K as well as total alpha and total beta. Results indicated that the radioactivity level of water bodies was within normal natural background,without contamination by artificial radioactive nuclide.
