Procedure for 107Pd determination in radioactive wastes coming from decommissioning of NPP A-1 is proposed and verified. 107Pd was separated and purified by Pd precipitation with dimethylglyoxime (DMG) and/or ferric hydroxide precipitation. 107Pd yield was determined gravimetrically by weighing the Pd(DMG)2 precipitate. 107Pd counting was performed using liquid scintillation counter (LSC-TDCR) and scintillation cocktail Hionic Fluor. In all analyzed samples the determined activities of 107Pd were lower than MDA
