In the problem of global shortage of Mo-99/Tc-99m and the progress of targeted radionuclide therapy, the production of medical nuclide using accelerators has been attracting attention. An electron linear accelerator based medical radioisotope production system has many advantages in comparison with other accelerator systems: the size of the system is relatively small, increasing of the amount of raw material nuclide is easily achieved, the production amount of impurity nuclides is very little and the cross section of medical radioisotope production reactions are relatively high. These advantages can lead to a cost-effective system. In this paper, we introduce our recent efforts in experimental and simulated studies of the production of Mo-99, Cu-67 and Ac-225 using electron linear accelerator.
