The invention provides a method for producing 47Sc by
irradiation of a medium-high-energy accelerator, which comprises the following steps: producing 47Sc by using a medium-energy section and a low-energy section of a 50MeV high-current
proton cyclotron and adopting an indirect production mode and a
direct production mode, and forming a composite target by a target material for indirectly producing the 47Sc and a target material for directly producing the 47Sc; in the middle energy section, the target material for indirectly producing
nuclide is adopted to produce 47Sc, and the indirectly produced target material is that after the target material reacts with protons, parent
isotope nuclide is firstly produced, and then
daughter isotope 47Sc is produced through parent
isotope decay; in the low-energy section, the target material for directly producing
nuclide is adopted to produce 47Sc, the
direct production of the target material means that the 47Sc is produced by using the optimal
energy interval of the target material, and the optimal
energy interval means that the isotope
impurity in the interval is relatively 0; the 47Sc is directly or indirectly produced, the energy of a medium-
high energy accelerator is fully utilized, and the produced 47Sc has the advantages of high yield and high purity and can meet the requirements of future market products.
