摘要

This study demonstrates the potential of gamma spectrometry coupled with electrodeposition as a sample preparation technique for determination of 55Fe in complex solid samples with high iron content. Electrodeposition has proven to be a reliable method for obtaining thin, homogeneous films containing up to 50 mg of total iron. In contrast, ammonium pyrrolidinedithiocarbamate precipitation method shows inhomogeneity and significant film thickness at 0.5 mg of iron. The efficiency correction function for gamma-spectrometric measurements based on the total iron content was introduced.
