为全面了解江西省集中式供水中放射性含量，保证公众健康，对全省１０个地（市）的县级以上８２个水源水和８７个自来水进行总α、总β放射性活度测定。采样方法：打开水龙头，放水５ｍｉｎ，然后用洗净的１０Ｌ塑料桶采样，加入５ｍＬ浓硝酸，以防桶壁吸附放射性核素。检验按
In order to fully understand the radioactive content of centralized water supply in Jiangxi Province and ensure the public health, the total α and total β radioactive activities of 82 water sources and 87 tap water sources above the county level in 10 provinces (cities) in the province were measured. Sampling method: Turn on the faucet, drain 5min, and then use a clean 10L plastic bucket sampling, adding 5mL concentrated nitric acid to prevent the absorption of radionuclides barrel wall.
