Examination of a Method for Rapid Determination of Strontium-90 in Agricultural and Livestock Products, Indicator Plants Using Solid-phase Extraction with DGA Resin
plants by means of solid-phase extraction with DGA resin. The resin is then used to determine 90 Sr by detection of yttrium-90 ( 90 Y), which exists in secular equilibrium with 90 Sr. The method was tested on 90 Sr-spiked samples (milk) and a certified reference material (IAEA-330), and the trueness values were 108% and 107% for milk, 111% for IAEA-330. In addition, stable Y recoveries exceeded 0.81 in the tests. The ratio of values measured by our examined method and the conventional method ranged from 0.75 to 1.15, and the 90 Sr detection limit ranged from 0.02 to 0.05 Bq/kg fresh weight. The sample-throughput time for the examined method was approximately 3 weeks shorter than that of the conventional method.
