白龙江下游涉核地区水的放射性环境水平现状调查

The Radioactive Environmental Survey in the Lower Reaches of the Bailong River

通过白龙江下游涉核地区水的放射性环境水平调查,得出白龙江下游涉核地区的区域内水中铀、镭浓度普遍较低。U含量在0.35～5.42μg/L,Th含量水平极低,Ra在0.36～1.32Bq/L之间。通过分析,水中铀、镭浓度的相关性不一致,可知道在某些河段的铀、镭平衡已经被破坏,成为偏镭系的铀、镭平衡。

The radioactive environmental survey indicates that U and Ra contents in water in the lower reaches of the Bailong River are low with U of 0.35-5.42 ppm and Ra of 0.36-1.32 ppm.No correlation of U with Ra indicates that U-Ra balance has been upset in some sectors.
