摘要
本文利用放射化学分析法测定了长江口及其邻近陆架沉积物中^(226)Ra和^(210)Pb的含量。结果表明,在该海区的沉积物中,^(226)Ra含量的水平分布随经度增加而直线下降,而^(210)Pb含量的水平分布则随经度增加而直线上升,二者形成明显的同步反向分布。
This paper reports the determination and distribition of 226Ra and 210Pb in the sediments of Chang Jiang River Estuary and its adjacent continental shelf. The contents of 226Ra in the sediments decreases gragually with the increase of longitude, but the contents of 210Pb does the opposite.
