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.

通过LSC和2πα计数标准化非平衡²¹⁰ Pb溶液

已经建立并成功验证了放射性不平衡中²¹⁰ Pb溶液或从其后代中未完全纯化的标准化方法。该方法基于通过α粒子光谱法（2πα计数）与网格电离室和液体闪烁计数法联合测量²¹⁰ Po的总活性，提出了该方法，替代了用α/β鉴别的LSC测量²¹⁰ Pb。
