Standardization of 226Ra solutions with descendants by 4παβ LSC counting.

Abstract In this work, a method to standardize 226Ra solutions with descendants by 4παβ liquid scintillation counting (LSC) has been used. The standardization can be carried out provided that the equilibrium state of 226Ra solutions, the counting efficiency of short-lived 214Po and/or the counter dead time are known. Procedures to obtain these requirements have been set up.
