A numerical model simulating the distribution of Ве in the Black Sea was developed and applied to study the spatial and temporal variations in the content of Be in the surface waters. Variations in the distribution of Ве were analyzed for the period from January to December of 2012. The average seasonal content of Ве in the surface layer ranges from 2.2 to 6.2 Bq m. The maximum concentration is typical for the eastern part of the sea in winter to spring, and the minimum concentration is typical for the central and western parts of the sea in summer. The seasonally averaged activity of Ве on suspended matter ranges from 440 to 1560 Bq kg. The highest values are observed in the sea in winter to spring, and the lowest values are typically observed in the central and western parts of the sea in summer. It was revealed that the adsorption of Ве on suspended matter is most significant for the evolution of the content of this radionuclide in shelf waters.
建立了一个数值模型来模拟Ве在黑海的分布，并应用该模型来研究表层水中 Be 含量的时空变化。分析了 2012 年 1 月至 12 月期间 Ве 分布的变化。表层水中 Be 的平均季节含量范围为 2.2 至 6.2 Bq m。冬季到春季，海东部典型的最大浓度，夏季则是海中部和西部典型的最小浓度。悬浮物质上的 Be 季节平均活性范围为 440 至 1560 Bq kg。冬季到春季观测到的最高值，夏季海中部和西部典型的最低值。结果表明，Be 在悬浮物质上的吸附对陆架水这种放射性核素含量的演变最为显著。
