| 内容記述 | [Aim] We evaluated the production feasibility of Ac-225 (T1/2 = 10 d, decay to Bi-209 via 4α+2β) by using Ra-226 target coupled with our vertical irradiation system. [Method] Radium targets of 100–500 μCi (nearly equal to the unit of μg) added with carrier calcium were prepared as carbonate by precipitation on a silicon carbide filter. Irradiations were performed with 18 MeV protons at 3 μA for 3 h. The Ac-225 product, purified by the following filtration, radio-colloid formation, reconstitution, and column separation, was obtained in a dried form. [Results and Discussion] Production yields of Ac-225 strongly depend on the amount of Ra-226 prepared, where the produced activity of Ac-225 was roughly estimated to be about 1/100 of the Ra-226 activity by the above irradiation condition (9 μAh); e.g., approximately 5 μCi of Ac-225 can be obtained from a 500 μCi of radium target. |
