目的对我区部队小型集中式供水水质进行总α、总β放射性检测,评价小型集中式供水水质是否达到《生活饮用水卫生标准》放射指标标准,确保广大官兵的健康。方法样品处理、标准源制备和检测均采用《生活饮用水标准检验方法—放射性指标》推荐的方法进行,所使用的试剂均符合《生活饮用水标准检验方法—放射性指标》要求,运用BH1216Ⅱ型低本底α、β测量仪进行样品总α、总β放射性检测。结果参照《生活饮用水卫生标准》,所检测样品总α均低于0.5 Bq/L、总β放射性均低于1 Bq/L的标准要求。结论小型集中式供水水质符合国家标准,可放心饮用。
Objective To detect the total α and total β radioactivity of small centralized water quality in our district and assess whether the quality of small centralized water supply meets the radioactive standard of “drinking water health standard” to ensure the health of officers and men. Methods Sample preparation, standard source preparation and testing were all carried out by the method recommended by Standard Test Method for Drinking Water - Radioactivity Index. The reagents used met the requirements of “Standard Test Method for Drinking Water Quality - Radioactivity Index”, and used BH1216 Type II Low Background α, β measuring instrument for the total sample α, total β radioactivity detection. The results refer to “drinking water health standards”, the test samples total α are less than 0.5 Bq / L, total β radioactivity were lower than 1 Bq / L standard requirements. Conclusion The small centralized water quality conforms to national standards and can be safely consumed.
