Abstract

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.
