[en] The paper reports details of a project undertaken to establish the feasibility of producing carrier-free ²⁰¹Tl in Australia in quantities suitable for human diagnostic use. The cyclotron at the Australian National University was used in the tests. Maximum beam energy of 26 MeV at 40μA yielded an achievable production rate of 4mCi per hour thallium 201. The final separated product proved to be compatible in purity with the only other published data and its efficacy as a myocardial imaging agent was successfully demonstrated in animals. Liaison with the Australian Atomic Energy Commission has begun with a view to satisfying locally the growing demand for this nuclide
