摘　　要：采用裂变径迹分析技术测定了饮料和矿泉水中的铀含量。结果表明,饮料中铀含量为0.26±0.03～1.65±0.07ppb,其平均值为0.93±0.05ppb;矿泉水中铀含量平均值为9.20±0.16ppb,为饮料中平均铀含量的10倍。Trace U in beverages and mineral water has been estimated using the fission track an-alysis technique. The U contents in beverages vary from 0.26 ± 0.03 to 1.65±0.07 ppb, with an average of 0.93±0.05ppb. The mean U content in mineral water is 9.20±0.16 ppb, which is 10 times higher than that in other beverages.
