Quantitating iron (Fe) isotopes, Fe-55 and Fe-59, radiometrically can be difficult due to emission interferences or high spectral backgrounds due to the presence of other activation products or fission product contaminants. The purpose of this work was to demonstrate a separation procedure for Fe activation products from complex samples that contain either activated soil components or freshly produced fission products generated from highly enriched uranium. The developed procedure succesfully allowed for quantitative analysis of both the Fe-59 (by gamma spectroscopy) and Fe-55 (by low energy photon spectrsocopy) with > 90% elemental recovery.
