This paper presents the radioactivity measurement of Danube River sediment samples collected during 2018 by the National Institute of Hydrology and Water Management from the Giurgiu-Isaccea sector and Danube Delta branches (22 samples). Activity concentration of natural radionuclides from 238U-226Ra and 232Th radioactive series, 235U, and 40K, as well as 137Cs man made radionuclide were determined by gamma-ray spectrometry at the Horia Hulubei National Institute of Physics and Nuclear Engineering. Mass fractions of U, Th, and K were also assessed. The results are compared with previously obtained data on Danube sediments collected in expedition campaigns between 1991 and 1997, as well as literature data. |
