Annual and Seasonal Variations in the Gamma Activities in Sava River Sediments Upstream and Downstream of NPP Krško

Results of the five years monitoring of artificial and natural occurring radionuclides in the Sava River sediments are presented. Measurements were conducted as a part of the regular Krško Nuclear Power Plant radioactivity control and the independent supervisions of the input of radionuclides into larger environment (imission). In order to estimate seasonal variations, samples were taken from seven locations (one upstream and five downstream of the Krsko NPP) during four sampling periods (seasonal) in each year. Selected radionuclide in the sediment fraction less than 0.5 mm were determined with gamma spectrometer equipped with BE3830 model High Purity Ge detector with 30% relative efficiency.
