AB This report presents a new methodology to isolate and measure 210Po, as well as uranium and thorium isotopes. This new methodology reduces the standard time of operation, the minimum amount of chemical reagents and the quantity of resin used in comparison with other standard and well-established procedures for alpha spec- trometry. Thus, the amount of chemicals reagent was lower than the amount used in other standard radio- chemical processes: only 6 mL of 1 M HCl was used for the thorium elution, and 2 mL of H2O and 1 mL of Ammonium Oxalate (0.05 M) (3 mL in total) for the uranium elution. Likewise, many samples of various ac- tivities and materials (liquids and solids) were used to validate the method.
