Title: Electron linear accelerator production and purification of scandium-47 from titanium dioxide targets

Here, the photonuclear production of no-carrier-added (NCA) 47Sc from solid NatTiO 2 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 TiO 2 targets were dissolved in fuming H 2SO 4 in the presence of Na 2SO 4 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).
