Production of 98Tc with high isotopic purity

Appl Radiat Isot. 2020 Jun;160:109133. doi: 10.1016/j.apradiso.2020.109133. Epub 2020 Mar 16.


In this work, technetium-98 (98Tc) was prepared with high isotopic purity via the nuclear reaction 98Mo (p, n) 98Tc for the first time. An enriched 98Mo metal target formed by spark plasma sintering was bombarded with 9.4 MeV protons in a CS-30 cyclotron. A microgram amount of 98Tc with 99.18% isotopic purity was separated from the irradiated target by anion exchange chromatography. Additionally, a chemical procedure for recovering the enriched 98Mo with a 97% recovery rate was developed.
