摘　　要：目的了解郑州市不同地区、不同季节、不同水源类型的放射性水平。方法分别于丰水期和枯水期采集郑州市区黄河水源水、井水源水、丹江口水源水、出厂水和末梢水各一份;以县为单位,每单位采集出厂水、末梢水、水库水、河水、井水各1份,按《生活饮用水生活标准检验方法》(GB/T 5750.13-2006)检测饮用水中总α和总β放射性水平,依据《生活饮用水卫生标准》(GB 5749-2006)进行判定。结果丰水期、枯水期水体总α、总β放射性水平均低于国家标准限值。结论郑州市不同水源类型均处于正常的天然放射性本底水平。Objective To investigate the radioactivity level in drinking water for different areas,different seasons and different types in Zhengzhou. Methods In wet and dry season,we collected Yellow River source water,well water,danjiangkou hydroelectric source water,finished water and tap water each one from Zhengzhou city,collected finished water and tap water reservoir water,river water,well water each one from Zhengzhou countries. The radioactive concentration of gross α a and gross β were testing according to Standard Method for Detecting Living Drinking water,judging by Hygienic Standard for Drinking Water. Result The radioactive levels of gross α and gross β were all lower than limit issued in national standard. Conclusions The level of radioactive levels were normal in all kind of water in Zhengzhou. We should keep monitoring for the water safety.
