目的调查分析青海省海西地区居民生活饮用水中总α、总β放射性水平情况。方法依据生活饮用水卫生标准检验方法(GB/T 5750.13-2006)对青海省海西地区出厂水和水源水共计71份水样进行检测。结果检测水样(水源水和出厂水)的丰水期和枯水期之间总α和总β放射性水平比较差异无统计学意义。结论青海省海西地区生活饮用水中放射性水平处于正常本底范围内,通过多布点、每年两次等方式进行动态监测,确保居民饮水安全。
Objective To investigate the total α, total β radioactivity in drinking water of residents in Haixi region of Qinghai Province. Methods A total of 71 water samples from factory water and source water in Haixi area of Qinghai Province were tested according to the standard of sanitary drinking water standard (GB / T 5750.13-2006). Results There was no significant difference in total α and total β radioactivity between the wet and dry periods of water samples (water source and ex-factory water). Conclusion The radioactivity level of drinking water in Haixi region of Qinghai Province is within the normal background range. The dynamic monitoring is carried out by means of multiple distribution points, twice a year, etc. to ensure residents’ drinking water safety.
