The 238,239+240Pu activity concentrations in sediments and in water in the Crimean salt lakes were studied. Activity ratio of 238Pu/239+240Pu in depth profiles of sediments was used to estimate the contribution of two main sources of man-made plutonium to the Pu sediment inventory. The most part of the plutonium was of global origin. Concentration factor of the plutonium isotopes in sediments, radiocapacity factor of the lake, the type of biogeochemical behavior of plutonium in these reservoirs and the sediment inventory of 238,239+240Pu in the lakes were evaluated.

克里米亚盐湖底部沉积物和水中钚同位素的活度浓度

研究了克里米亚盐湖中沉积物和水中的 238,239+240Pu 活性浓度。沉积物深度剖面中 238Pu/239+240Pu 的活度比被用来估计人造钚的两个主要来源对 Pu 沉积物清单的贡献。大部分钚来自全球。评估了沉积物中钚同位素的浓度因子、湖泊的放射性容量因子、钚在这些水库中的生物地球化学行为类型以及湖泊中 238,239+240Pu 的沉积物清单。
