(Table 1) Concentration of plutonium isoptopes in dry matter of bottom sediments from the Kerch Straight area in December 2007

A study of redistribution of alpha-radioactive isotopes of plutonium, 239,240Pu and 238Pu in coastal ecosystems off the northern Black Sea coast for quantitative characterization of modern radioecological situation in these waters with respect to plutonium was the aim of this work.

本研究旨在探究黑海北部沿岸近海生态系统中钚的239,240Pu与238Pu这两种α放射性同位素（alpha-radioactive isotopes）的再分布规律，从而定量表征该海域当前针对钚的放射生态现状。
