Determination of actinides in Sava river sediments upstream and downstream of NPP Krško by low-level alpha spectrometry

A rapid, sensitive and selective procedure is described for determination of Pu, Am, and U in environmental samples by electrodeposition technique. To determine the optimum conditions for plating actinides parameters affecting the electrodeposition such as plating time and current were investigate. Actinides were plated from ammonium oxalate-ammonium sulfate electrolyte containing diethyltriammino pentaacetic acid (DTPA). Total activity of actinides in Sava river sediments upstream and downstream of NPP Krško was investigated. The optimized method was validated by application to environmental samples. Microwave digestion system was used for total decomposition of sediment samples. The chemical yield of plated actinides was determined by 232U.
