Standardization of non-equilibrium 210Pb solutions by LSC and 2πα counting.
2021
A procedure for the standardization of 210Pb solutions in radioactive disequilibrium, or incompletely purified from its descendants, has been set up and successfully validated. The method, based on joint measurements of 210Po by alpha-particle spectrometry (2πα counting) with grid ionization chamber and liquid scintillation counting for overall activity estimation, is presented as an alternative to 210Pb measurement by LSC with α/β discrimination.
