目的了解青海省地下水饮用水源总α、总β放射性水平。方法用BH1216低本底α、β测量装置对121个地下水饮用水源总放射性水平进行检测及评价。结果水样总β放射性活度浓度在Ⅰ~Ⅲ类;34.71%水样总α放射性活度浓度属于Ⅰ~Ⅲ类,65.29%水样总α放射性活度浓度在Ⅳ类。深井和泉水饮用水源总α、总β放射性活度浓度差异有统计学意义(P<0.05)。结论青海省地下水饮用水源未受到人工放射性核素的污染。
Objective To understand the total α and total β radioactivity of groundwater drinking water in Qinghai Province. Methods The total radioactivity of 121 drinking water sources in groundwater was measured and evaluated by BH1216 low background α, β measuring device. Results The concentration of total β radioactivity in water samples was in the range of Ⅰ ~ Ⅲ. The total radioactive radioactive concentrations of 34.71% of water samples belonged to Ⅰ ~ Ⅲ, and the total α radioactivity of 65.29% of samples was in Ⅳ. The concentrations of total α and total β radioactivity in deep well and spring drinking water were significantly different (P <0.05). Conclusion The drinking water source for groundwater in Qinghai Province is not polluted by artificial radionuclides.
