摘要
本文报告了四川省 5种饮用水总放射性的监测结果 ,发现各类饮用水之间总放射性比活度检出结果差异较大。经处理的出厂自来水相对较低 ,地下水较高。 90个自来水样总α检出合格率为 96 % ,总 β合格率为 10 0 %。对总α超限值水样建议进行核素2 2 6Ra检测 ,而且2 2 6Ra的含量不应超过总α限值。
In this paper, monitoring results of 5 kinds of drinking water in Sichaun Province are reported. The results showed that total radioactivity among these drinking water are different from each other greatly. The tap water is lower, whereas groundwater is higher. The total α of 96% tap water samples meets the standard,while the total β of all tap water meets the standard. It is necessary to detect the 226 Ra level of water samples which α radioactivity exceeds the α limit. For drinking water, its 226 Ra level must be lower than the α limit.
