Abstract  

A method is described for the determination of89Sr and90Sr in samples of plant and animal origin. The Rehak-Feddersen method was modified to measure90Sr. Modification was made in the sample preparation and in the toluene-HDEHP [di(2-ethylhexyl)phosphoric acid] extraction. After the extraction of yttrium, strontium is separated with nitric acid and—calculating with a correction factor—89Sr can directly be determined. Namely,89Sr can be measured in an aqueous solution by a liquid scintillation technique with an efficiency of 30% while90Sr with 1.4% only. Quenching of the solution—depending on the composition—which may influence the measurement of90Y and89Sr was also examined. Detection limits and reproducibilities are given. Finally, evaluation of the experimental data is reported.
