A rapid separation method has been developed which allows measurement of plutonium, americium and strontium isotopes in the
radioactive sludge from Nuclear power plant A1 Jaslovske Bohunice (NPP A1) with high chemical recoveries and effective removal
of matrix interferences. This method uses different commercial products stacked AnaLig® Pu02, AnaLig® Sr01 and TRU® Resin cartridges from IBC Advanced Technologies and Eichrom Technologies. The method allows the rapid separation of plutonium,
strontium and americium using a single multi-stage column in the vacuum box (cartridge technology) with rapid flow rates to
minimize sample separation time. The 239,240Pu, 238Pu and 241Am were determined by alpha spectroscopy, 90Sr was counted on TRICARB 2900 TR by Cerenkov counting of its progeny 90Y.

Procedure for analysis of plutonium isotopes in soil samples was developed using a new molecular recognition technology product
AnaLig®Pu-02 gel. Extraction chromatography TEVA® Resin was used for purification of plutonium phase to remove thorium impurities which interfere in Pu determination by alpha
spectrometry. The performance of the method was successfully tested by analysis of a sand stimulant sample and a soil sample
spiked with known activity of 239Pu. The results obtained for procedures were compared in terms of activities and recoveries.
