Quantitation of lead-210 (²¹⁰Pb) using lead-203 (²⁰³Pb) as a "Massless" yield tracer.

ABSTRACT: Determination of Pb-210 (²¹⁰Pb) in aqueous solution is a common radioanalytical challenge in environmental science. Widely used methods for undertaking these analyses (e.g., ASTM D7535) rely on the use of stable lead (Pb) as a yield tracer that takes into account losses of ²¹⁰Pb that inevitably occur during elemental/radiochemical separations of the procedures. Although effective, these methods introduce technical challenges that can be difficult to track and potentially introduce uncertainty that can be difficult to quantify. Examples of these challenges include interference from endogenous stable Pb in complex sample matrices; contamination of stable Pb carrier with ²¹⁰Pb; and high detection limits due to counting efficiency limitations. We hypothesized t
