摘　　要：目的总结和分析2008年-2011年兰州市及周边地区生活饮用水、地下水及沟渠水放射性水平,为熟悉掌握水资源提供科学依据,以期为扩大饮用水水源地提供指导。方法以生活饮用水、地下水、沟渠水作为分析对象,依据国家标准GB/T 5750.13-2006和GB/T 8538.13-2008对水样总放射性水平进行分析。结果生活饮用水总放射性符合《生活饮用水卫生标准》。按《生活饮用水卫生标准》,地下水总α放射性超标的水样占5.5%,总β放射性超标的占0.9%;沟渠水总α、β放射性超标的均占2.4%。结论兰州市及周边地区的生活饮用水未受到辐射污染,符合生活饮用水要求;地下水和沟渠水部分已受到射辐污染,必须严格检验,否则不适宜作为居民生活用水水源。Objective To summarize and analyze radioactivity level of the surrounding areas drinking water,groundwater and ditch water in Lanzhou City from 2008 to 2011,and provide a scientific basis for mastering the water resources,and the guidance for the expansion of drinking water sources. Methods Taking drinking water,ground water,ditches water as material,the total radioactivity levels in water samples were analysed according to the national standard GB /T 5750. 13- 2006 and GB /T8538. 13- 2008. Results The total radioactivity of drinking water results was in line with ＂the drinking water health standards＂; and according to this standards,the ground water samples which exceeded total α radioactive was more than 5. 5%,and the exceeded total β radioactivity was 0. 9%; the ditch water sample total exceeded α,β radioactivity both accounted for2. 4%. Conclusion The drinking water of Lanzhou city and the water in surrounding area was not contaminated by radiation,and in line with the requirements of drinking water. The groundwater and ditch water has contaminated partially by radiation,which must be strictly tested,otherwise was not suitable for living water sources.
