Electrodeposition of silver on copper substrate was carried out using alkaline plating baths for production of Cadmium-109 via the nat Ag( p, n) 109 Cd nuclear reaction. The target could withstand 15 MeV proton beam currents of up to 150 µA; the 109 Cd production yield was 1.88 µCi/µA h (0.069 MBq/µA h). Cadmium-109 was separated from silver and non-isotopic impurities by ion-exchange chromatography.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
