Vertical distribution of anthropogenic radionuclides in cores from contaminated floodplains of the Yenisey River (original) (raw)

The study investigates the vertical distribution of anthropogenic radionuclides in contaminated floodplains along the Yenisey River, focusing on the contamination resulting from the Krasnoyarsk-26 Mining and Chemical Combine (KMCC) operations. Various sediment samples were analyzed to determine the association of radionuclide concentrations, specifically Cs-137 and Pu-239,240, with sediment size fractions. Findings reveal significant variations in radionuclide activity concentrations, correlated with specific sediment characteristics, providing insights into historical discharge patterns and sedimentological processes.
