Antimony-119 (38.19 h, 100% decay) holds promise in targeted radionuclide therapy because of its unique Auger electron energy spectrum and potential for production on small medical cyclo-trons. Production, however, is hindered by the relatively low natural isotopic abundance of 119Sn. To apply 119Sb in preclinical experiments, GBq quantity and high radioisotopic purity needs are anticipated. The use of natural isotopic abundance tin targets produces significant radioisotopic im-purities. Sustainable productions will require reclamation of enriched Sn target material. This work investigates electrodeposition and subsequent recovery of natural Sn targets.
