云南省水体总α、总β放射性水平分析

Analysis of the Radiation Level of Total α and β in the Water Body of Yunnan Province

摘要: 对云南省水体样品采集检测,调查了解云南省水体总α、总β放射性活度。枯水期总α、β全省平均放射性活度为0.017Bq/L、0.069Bq/L;丰水期为0.042Bq/L、0.066Bq/L。云南省水体总α、总β放射性水平均远低于国家《GB 5749-2006生活饮用水卫生标准》规定的总α、总β放射性活度限值,放射性水平整体状况较好。

Abstract: The Radioactive activity of total α and β in the water body of Yunnan province was surveyed by monitoring the water samples. The radioactive activity of totalαandβin dry season were 0. 017 Bq/L,0. 069 Bq/L,respectively. They were 0. 042 Bq/L and 0. 066 Bq/L in rainy season. The radioactive activity of them is far lower than the limit in the national standard of"Standard for Drinking Water Quality"(GB 5749-2006). Therefore,the general radioactive activity of the water body of Yunnan is good.
