Abstract

A method has been developed for measuring90Sr activity in liquid samples. After concentrating strontium from the sample by coprecipitation with calcium phosphate, the residue is dissolved in 8N HNO3 and passed through an extraction chromatographic column (Sr.Spec) containing a new material that selectively retains strontium. This is eluted from the column with 0.05N HNO3 and counted by liquid scintillation. Measurement is performed using a double window method, that allows a rapid and single determination of90Sr.
