| 通过对地震后雅安市芦山县的饮用水水源地总放射性水平调查，初步掌握该县重点区域饮用水水源地放射性浓度的水平。参考《生活饮用水标准检验方法〓放射性指标》（GB/T 5750.13—2006），通过测定质量厚度-计数效率曲线获取不同质量厚度的样品源所对应的计数效率值，计算水质中总放射性浓度。结果显示，所采集的雅安芦山地震灾区40个饮用水源地水样中的总α、总β放射性活度浓度范围分别为9.13×10-3 Bq/L～9.83×10-2 Bq/L和1.68×10-2 Bq/L～1.36×10-1 Bq/L，均符合我国《生活饮用水卫生标准》(GB 5749—2006)中放射性活度浓度指标限值要求（总α≤0.5 Bq/L，总β≤1 Bq/L）。说明地震没有造成该地区饮用水源地水质的放射性污染。 |

| In this paper, the gross α and gross β radioactivity levels of drinking water sources in Lushan county were investigated after the earthquake, and the radiation concentrations in the core area of the county were obtained. Referring to the Standard Examination Methods for Drinking Water Radiological Parameters (GB/T 5750.13—2006), the total radiation concentration was calculated by counting the efficiency value of different mass thickness samples according to mass thickness efficiency count curve. The results of 40 samples from drinking water sources in the earthquake disaster area showed that the concentrations of gross α and gross β ranged from 9.13×10-3 Bq/L to 9.83×10-2 Bq/L and 1.68×10-2 Bq/L to 1.36×10-1 Bq/L, respectively, both within the standard limit (gross α≤0.5 Bq/L,gross β≤1 Bq/L) of Standards for Drinking Water Quality(GB 5749—2006). The earthquake caused no radioactive pollution to drinking water quality. |
