摘要
人工放射性元素Pu在中国海岸带中的传输关系到国家核安全应急与海洋生态安全,在放射化学、海洋学、生态学、地球科学等领域具有重要的监测意义。中国海岸带处于西北太平洋边缘海区域,其强浊流环境的特征使得在该环境中洋流传输来的放射性物质Pu或其他人工放射性物质与海水中的悬浮物发生迅速的清除廓清作用。Pu在海洋沉积环境中发生明显的迁移作用,对其同位素指纹特征与其他地球化学指标的研究能迅速判别出放射性污染物质的来源与各自比率关系。该文综述了近几十年来Pu在中国海岸带环境中的研究进展,海岸带Pu的研究有助于国家核电战略与复杂外部海洋等环境下的海岸海洋核安全、地球环境变化的瞬时评估、突发核事故状态下的核应急保障。
The transport of the artificial radioactive element Pu(Plutonium)in China's coastal zone is related to national nuclear safety and emergency response and marine ecological safety,which is of great significance for monitoring in the fields of radiochemistry,oceanography,ecology and earth sciences.China's coastal zones are located in the marginal sea areas of the Northwest Pacific Ocean,also characterized by strong turbidity currents,making it possible to rapidly scavenging and contami⁃nate the suspended sediments in seawater with Pu or other artificial radioactive substances transported by ocean currents,and the extensive migration of Pu in the marine sedimentary environment.The study of its isotopic fingerprints and other geochemical indexes can quickly identify the sources of ra⁃dioactive and respective the proportion of radioactive contaminants.This paper summarizes the re⁃search progress of Pu in Chinese coastal zone environment in recent decades.The study of Pu in the coastal zone will contribute to the national nuclear power strategy and the nuclear safety of the coastal areas under the complex external marine environment,the instantaneous assessment of changes in the earth's environment,and the nuclear emergency safeguard in case of a nuclear accident.
