Activity concentration of plutonium isotopes in bottom sediments and water in Crimean salt lakes

The 238,239+240 Pu activity concentrations in sediments and in water in the Crimean salt lakes were studied. Activity ratio of 238 Pu/ 239+240 Pu 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...

Summary:The 238,239+240 Pu activity concentrations in sediments and in water in the Crimean salt lakes were studied. Activity ratio of 238 Pu/ 239+240 Pu 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+240 Pu in the lakes were evaluated.
