饮用水和生活用水中的氡及其研究现状

劣质饮用水是导致人群体质下降、营养代谢疾病早期化的主要原因。水中析出的氡被人体长期摄入,会对胃、肺等组织产生辐射影响。发达国家饮用水的水质检测项目多达350项,其中,衡量饮用水氡水平的是最大污染水平。我国目前饮用水水质检测项目仅为35项。城市自来水、瓶(桶)装蒸馏水、矿泉水、纯净水等,农村深井水、地表天然水的氡检测及市场调查前景广大。

Radon Concentration in drinking water and water for living use and their study status

Low quality water is the chief reason for resulting in decrease of human group's physique,and in early appearance of nutrition and supersession deseases.The assimilation of radon released from water by human body may cause radioactive impact to those organs such as stomach and lungs.The monitoring determination for chemical quality of drinking water in developed countries comprises as many as 350 items,and the maximum contamination level of international standards is adopted for checking the radon concentration in drinking water,However,at present,only 35 items of the chemical quality of drinking water are determined in China.The monitoring determination of radon concentration in running water of cities,in distillation water,mineral water,pure water,deep well water in country side,as well as natural surface water is of great market potential in the future.
