Abstract
The paper presents the results of modeling the production of a medical isotope using the medical isotope browser of the International Atomic Energy Agency. A web application for the production of medical isotopes allows you to obtain the necessary data on a nuclear reaction based on user data: target radionuclide, irradiating particle or irradiating radiation, energy range, irradiation and cooling time. Tabular values and illustrated graphs of the cross section of the nuclear reaction are obtained based on modeling the production of the isotope iodine-123 from tellurium-124; The isotope decay products are presented. The simulation results were compared with the data recommended by the IAEA for this nuclear reaction for the gamma-emitting radionuclide iodine-123. It is shown that gamma-emitting radionuclide iodine-123 is one of the most convenient radionuclides for single-photon emission computed tomography. When experimental methods are not available, modern technologies in the field of computer modeling allow specialists in a narrow profile to use the achievements of world science to solve problems, in this case, for the production of medical isotopes. Modeling approaches for the production of iodine-123 are recommended for the production of other medical isotopes.
