Some man-made and natural radionuclides in the bottom sediments of the Caspian sea

Full text : The aim of this study was determination Radionuclides concentration in Caspian Sea sediments in Azerbaijan sector. For the study of the distribution of radionuclides in sea sediment was chosen south-east part of Caspian Sea as investigation zone on the basis of known Sea current systems and, the probability of a relatively uniform distribution of some radionuclides. The bottom sediments collected in different parts of the Caspian Sea were analyzed for some natural and man-made radionuclides. Sample preparation was spent on standard methods. The results confirm that the extraction, transportation and production of oil production in Azerbaijan sector of Caspian Sea didn't change radionuclide background in bottom sediments and dominant source of anthropogenic radionuclides in the Sea environment is global fallout and runoff from rivers Kura and Volga
