Abstract: Provided is a method capable of separating and purifying astatine-211 in a high yield and dissolving same in a solution. A method for producing astatine-211, including a step of irradiating α ray to bismuth to produce astatine-211 in the bismuth, and a step of distilling the bismuth that received α ray irradiation with a carrier gas containing an inert gas, O2 and H2O to separate and purify astatine-211, and dissolving the astatine-211 in a solution.

Abstract: There is provided a radionuclide manufacturing system, a computer-readable storage medium storing a radionuclide manufacturing program, a radionuclide manufacturing method, and a terminal device for more stably manufacturing a radionuclide.
A radionuclide manufacturing system includes: a heating unit configured to internally house a target holding a radionuclide; a gas supply unit; an adsorption unit configured to adsorb the radionuclide; a solvent supply unit; a storage unit configured to store a predetermined instruction; and a control unit configured to control the heating unit to heat the target at a temperature at which the radionuclide held in the target is allowed to volatilize, to control the gas supply unit to supply the carrier gas to the heating unit in order to transport the radionuclide volatilized in the heating unit to the adsorption unit, and to control the solvent supply unit in order to supply a solvent for eluting the radionuclide adsorbed to the adsorption unit to the adsorption unit based on the instruction.
