人工放射性核素及其地球化学行为的研究已成为当前海洋科学的重要内容之一。由于~(90)Sr是重要的裂变产物,在沉积化学、地球化学、海洋环境学和生物学的研究中都具有较重要的意义,故各国均比较重视。据统计,关于海水中~(90)Sr问题的研究最多,而沉积物较少。1981年,我们对渤海湾沉积物中的~(90)Sr进行了初步调查,根据所获资料,讨论了其分布规律和转移方式以及造成不同放射水平的原因。
Artificial radionuclides and their geochemical behavior has become one of the important contents of current marine science. As ~ (90) Sr is an important fission product, it is of great significance in the research of sedimentary chemistry, geochemistry, marine environmental science and biology, so all countries attach more importance to it. According to statistics, there is the most research on the problem of ~ (90) Sr in seawater, but few sediments. In 1981, we carried out a preliminary investigation of ~ (90) Sr in the sediments of Bohai Bay. Based on the data obtained, we discussed the distribution and transfer patterns and the causes of different radiation levels.
