Computer simulation and experimental investigation of Mo-99 yield in thick targets as a Tc-99m generator

The most important requirement for the production technology of radionuclides is to provide a high specific activity of the target nuclide as well as the full activity of the target. This problem can be solved by using a large volume of photonuclear targets, and then by the target nuclide radiochemical separation. Computer simulation and experimental study of the spatial distribution of the activity is carried out in this work for the molybdenum target. Optimal parameters of irradiation to achieve the maximum yield of isotopes Mo-99 (Tc-99m) from the molybdenum target have been found.
