Simulation of residual activity in steel and copper targets induced by 950 MeV/nucleon uranium ions

Radioactive nuclides will be produced in structures and surrounding materials of the relativistic heavy ion collider NICA. Predicting radioactivity in the materials, air, cooling water, and ground is an important part of the technical project. Some Monte Carlo transport codes (FLUKA, GEANT4, SHIELD) can simulate the production of radionuclides induced by heavy ions. The preliminary verification of MC codes with experimental data is necessary before using them for radiation protection purposes. In the present work, comparisons of the experiment and GEANT4 and SHIELD simulations of induced activity in thick stainless steel and copper targets irradiated with 950 MeV/nucleon uranium ions are presented.
