Production and Purification of Terbium-155 Using Natural Gadolinium Targets Terbium-155 (t1/2 = 5.32 days) is one of four medically relevant radioisotopes of terbium. It is of interest to the field as a suitable diagnostic counterpart for therapeutic radiolanthanides, as its decay scheme includes γ-rays that are suitable for single photon emission computed tomography (SPECT) imaging. Additionally, 155Tb has an Auger electron (AE) yield that is viable for AE therapy. There are several direct and indirect production routes that can produce 155Tb. Two possible direct routes include proton irradiation on gadolinium targets via 155Gd(p,n)155Tb and 156Gd(p,2n)155Tb. The 155Gd(p,n)155Tb reaction is accessible at incident proton beam energies of ∼10 MeV, whereas the 156Gd(p,2n)155Tb nuclear reaction requires ∼18 MeV. This study aims to investigate the production of 155Tb from natGd through the natGd(p,x) nuclear reaction, wherein both (p,n) and (p,2n) reactions were leveraged, and the purification using a three-column ion chromatography method. Using this system, recoveries of radioterbium of up to 97% were achieved in addition to high recoveries of the Gd target material, illustrating the suitability of this technique for enriched targets.
