Description

For the production of thallium-201 a target of at least 95% enriched pure lead-206 is irradiated by a proton beam of an energy of between 50 and 70 MeV. During irradiation the reaction 206Pb(p,6n)201Bi takes place. The target is kept sufficiently long for the transition 201Bi-201Pb-201Tl to take place. The target is then dissolved in acid. The thallium-201 contained in the acid is oxidized to the trivalent state followed by precipitation of the lead. Lead traces remaining in solution are separated from the thallium-201 through cation exchange following which the thallium-201 is eluted using hydrochloric acid
