摘要
利用激光荧光分析技术 ,采用标准加入法 ,对骊山地区温泉水、地热水及自来水中铀进行了分析。对 2 7个采样点 4 0个水样的分析结果表明 :骊山地区自来水中天然放射性铀浓度为～ 10 -6g/ L量级 ,地热水和温泉水中铀浓度为～ 10 -5g/ L量级 ,均属正常本底水平 。
Using the Laser Fluorescence technique, an investigation was made, adopting the standard mix method, on trace uranium concentrations in hot spring water and geothermal water from Lishan region, and in tap water from some major cities in Shanxi province. Totally 40 samples from 27 sites were investigated. Measurements showed that the tap water contains around 10 -6 g/L of uranium, whose concentrations in both hot spring water and geothermal water are 10 -5 g/L. Most of samples are at normal radioactive background level, some higher contents were determined in a few samples. (
