Abstract

The photonuclear production of no-carrier-added (NCA) ⁴⁷Sc from solid ^NatTiO₂ and the subsequent chemical processing and purification have been developed. Scandium-47 was produced by the ⁴⁸Ti(γ,p)⁴⁷Sc reaction with Bremsstrahlung photons produced from the braking of electrons in a high-Z (W or Ta) convertor. Production yields were simulated with the PHITS code (Particle and Heavy Ion Transport-code System) and compared to experimental results. Irradiated TiO₂ targets were dissolved in fuming H₂SO₄ in the presence of Na₂SO₄ and ⁴⁷Sc was purified using the commercially available Eichrom DGA resin. Typical ⁴⁷Sc recovery yields were >90% with excellent specific activity for small batches (<185 MBq batches).
