Abstract
Scandium-43 is an emerging PET radiometal that was produced by α-particle bombardment on natural CaCO3 target via natCa (α,p) 43Sc and natCa (α,n) 43Ti→43Sc reactions using K-130 cyclotron at VECC. A robust radiochemical procedure based on selective precipitation of 43Sc as Sc(OH)3 was developed for separation of the radioisotope from the irradiated target. The overall yield of the separation process was >85% and it was obtained in a form suitable for preparation of target specific radiopharmaceuticals for PET imaging of cancer.
