Simultaneous radionuclide determination using PSresin: 2in2 and 2in1 tandem configuration
Year: 2024
Type: article
Abstract: BACKGROUND: Sr and plutonium isotopes, may be present within various matrices. Given their distinct elemental properties, separation is typically achieved using different methods, followed by a measurement post-elution through alpha spectrometry and scintillation techniques. Therefore, methods which allow the fast and reliable determination of those mixtures are still required in routine laboratories. RESULTS: Sr and plutonium isotopes. Two strategies were investigated: using two PSresin in two cartridges and two measurements (2in2); and using two PSresin in a single cartridge and one measurement employing α/β discrimination (2in1). The methods were validated with standard solutions and applied to river water samples, achieving quantification errors below 10 % for both strategies within 5 and 8 h, respectively, from sample reception. SIGNIFICANCE: Sr and plutonium isotopes reduce the number of required analysis to half, reducing the overall time and cost of the analysis.
