Abstract

We report here results comparing the efficiency of three iodine extraction methods for the determination of 129I/I ratios in small samples. The direct organic extraction had the highest average yield. 129I/I ratios determined from targets prepared by direct organic extraction and silver extraction are comparable to each other within the error limits. The smallest sample from which a reliable 129I/I ratio was measured, started with an iodine input of 0.2 mg iodine and contained 0.14 mg AgI in the target.
