新疆集中式饮用水不同水源类型放射性水平对比分析

Comparative analysis of radioactive levels of different water source types of centralized drinking water in Xinjiang

本文调查了新疆某集中式饮用水不同水源类型总α、总β放射性水平,对不同的水源类型进行了数据对比,以为测量分析中出现的异常数据提供一个有效的鉴别依据。采集了新疆集中式饮用水不同类型水源经放化分析及测量总α、总β数值,得到新疆集中式饮用水不同水源类型放射性水平,并对不同类型的水源进行了对比分析。研究发现,总体上新疆某集中式饮用水不同水源类型的放射性水平基本处于正常环境本底范围,天然放射性核素水平未见异常;总α、总β的放射性浓度的高低是相依而存的,总α放射性浓度高的,其β的放射性浓度也高,总α放射性浓度低的,其β的放射性浓度也低;湖库型、河流型、地下水三种水源地的总α、总β的放射性浓度的高低的起因,主要包括其地理位置、水源类型等。

This paper investigates the total α and total β radioactivity levels of different water source types in a centralized drinking water in Xinjiang,and compares the data of different water source types in order to provide an effective identification basis for abnormal data in measurement analysis.The radiochemical analysis and measurement of total α and total β values of different types of Xinjiang centralized drinking water sources were collected to obtain the radioactivity levels of different types of Xinjiang centralized drinking water sources,and the different types of water sources were compared and analyzed.The study found that,in general,the radioactive levels of different water sources of a centralized drinking water in Xinjiang are basically in the normal environmental background range,and there is no abnormality in the natural radionuclide levels;the levels of total α and total β radioactivity are interdependent.The radioactive concentration of total α is high,the radioactive concentration of β is high,the radioactive concentration of low α is low,and the radioactive concentration of β is also low.The cause of the concentration level mainly includes its geographical location and water source type.
