摘要
本文报道了新疆维吾尔自治区河流、湖泊、水库、井、泉和自来水中 U、Th、^(226)Ra 和^(40)K 浓度的调查结果。全区共布设采样点76个,采集水样145个。调查结果表明,新疆各类水体中天然放射性核素浓度属正常本底水平,但发现局部区域水体中 U 浓度偏高。
This paper reports the investigation results of natural radioactivity level in river,lake,reser-voir,spring.well and tap water in Xinjiang.There were totally 269 samples collected from 124 measur-ing points.The results show that the radioactivity level of varied water bodies of Xinjiang was withinnormal natural background.
