本文研究了东海及冲绳海槽海水中钚的含量与分布,这对于研究放射性污染问题很有意义。该区表层水中Pu的含量为P.2—2.6×10~(-5)Bq/L,平均值为1.9×10~(-5)Bq/L,Pu的分布随物理化学特性和海洋条件的不同而呈不均匀分布状态。Pu/~(137)Cs为0.0036。浮游生物、海藻和生物悬浮体对Pu的浓缩能力很大。
This paper studies the content and distribution of plutonium in the seawater of the East China Sea and the Okinawa Trough, which is very meaningful for the study of radioactive pollution. The content of Pu in the surface water of this area is P.2-2.6 × 10 -5 Bq / L with an average value of 1.9 × 10 -5 Bq / L. The distribution of Pu varies with the physico-chemical characteristics and the marine conditions Different from the uneven distribution of the state. Pu / ~ (137) Cs is 0.0036. Plankton, seaweeds and biological suspensions have a great ability to concentrate Pu.
