Report on the Participation of Poland in the CRP on ''Small-Scale Indigenous Production of Mo-99 Using LEU Targets or Neutron Activation'' [Country report: Poland]

Technetium-99m (^99mTc), the daughter of molybdenum-99 (⁹⁹Mo) is the most commonly used radioisotope in nuclear medicine. Nearly all of the ⁹⁹Mo used is produced by the fission of ²³⁵U in high enriched uranium targets (HEU), generally 93% ²³⁵U. The replacement of low enriched uranium (LEU) targets for HEU targets requires many modifications in target fabrication and its chemical processing to efficiently separate ⁹⁹Mo. The aim of presented work were studies on the fabrication process of LEU foil target for irradiation in reactor, its disassembly, chemical dissolution and final ⁹⁹Mo separation.
