Sažetak
In order to estimate the influence of nuclear power plant and other industrial and agricultural anthropohenic sources on the quality of Sava river sediments, samples taken from seven locations (one upstream and six downstream of the Krsko NPP) were characterized. Seasonal variations in the sediment composition were determined on the basis of four samplings during the year 2004 (in February, May, October and December). Total concentrations of the elements Cr, Mn, Fe, Cu, Zn, Co and Pb in the sediment fraction less than 0.5 mm have been mesured by source excited energy dispersive X-ray fluorescence (EDXRF) while selected radionuclides were determined by gamma spectrometry. Mineralogical examination of the samples was performed using X-ray diffraction (XRD) method and alpha emitting radionuclides by low level alpha spectrometry.
