A New Method for Production of the Sr-82 Generator Radionuclide and Other Medical Radionuclides.

Abstract: A cyclotron (C-80) designed to produce protons with an energy of 40-80 MeV and beam intensity of 100-200 μA has been launched at the Petersburg Nuclear Physics Institute, National Research Center Kurchatov Institute. The main task of C-80 is the production of a wide range of medical radionuclides for diagnosis and therapy. A complex named Radioactive Isotopes on the C-80 Cyclotron (RIC-80) and intended to function on the C-80 beam was developed for this purpose. A brief description of the RIC-80 complex is given, and the results of the use of new methods and studies of target devices for the production of the generator radioisotope ⁸²Sr; ²²³Ra, ²²⁴Ra, and ²²⁵Ac radioisotopes that undergo alpha-decay; ⁶⁷Cu; and other medical radionuclides are presented. The use of a mass separator in the “on-line” mode to obtain ion beams of high-purity radioisotopes is a distinctive feature of the complex used in the project, and it is especially important for medical applications.
