摘要
本文介绍了日本金泽大学对环境中超铀元素的分布及行为的研究工作。采用新建立的放射化学方法和仪器,从日本各地收集表土、海湖沉积物、海水以及1954年“比基尼事件”的有关样品,研究了环境样品中的钚同位素、^(241)Am和^(237)Np的含量及其深度分布、随时间的变化以及和有机物的关系。
Research activities on distribution and behaviour oftransuranium elements in the environment at the Kanazawa University,Japan were presented. Using new developed radiochemical analysis methodsand instruments, and collecting the surface soil samples from variousareas of Japan, sectiments on the bottom of lake and sea,sea waterand those samples related to the Bikini event happened in.1954.The content of plutonium isotopes,^(241)Am and ^(237)Np in environmentalsample,their depth profile variation with time and the-relationshipbetween them with organic materials were studied.
