Rapid determination of ~(239,240)Pu, ~(238)Pu, ~(241)Am and ~(90)Sr in high contaminated samples waste using combined SPE sorbents AnaLig~? Pu-02, AnaLig~? Sr-01 and DGA~? Resin

摘要

A rapid separation method has been developed which allows measurement of plutonium, americium and strontium isotopes in the high active sample from CBRN Training and Testing Centre in Zemianske Kostolany (Slovakia) with high chemical recoveries and effective removal of matrix interferences. This method uses different commercial products stacked AnaLig~? Pu-02, AnaLig ~? Sr-01 and DGA~? Resin cartridges from IBC Advanced Technologies and Eichrom Technologies. The method allows 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 ~(239,240)Pu, ~(238)Pu and ~(241)Am were determined by alpha spectroscopy, ~(90)Sr was counted on TRICARB 2900 TR by Cerenkov counting of its progeny ~(90)Y.
