本文根据1980—1981年间渤海放射性调查获得的资料,探讨了渤海环境中~(90)Sr的含量分布及其变化规律。认为大陆径流以及~(90)Sr、~(137)Cs两核素被土壤吸附和从土壤中解吸的能力差异,是影响渤海环境中~(90)Sr分布及造成~(137)Cs/~(90)Sr比值严重反常的主要因素。
Based on the data obtained from the radioactive survey in the Bohai Sea from 1980 to 1981, this paper discussed the content distribution and its variation of ~ (90) Sr in the Bohai Sea. It is considered that the differences in the runoff and the ability of the two radionuclides (~ (90) Sr and ~ (137) Cs) to adsorb and desorb soil from the soil are related to the distribution of ~ (90) Sr in the Bohai Sea and the formation of 137 Cs / (90) Sr ratio serious abnormal factors.
