Abstract

This article focuses on the evaluation and modeling of radioactivity induced by particle accelerators, specifically medical linear accelerators (LINACs) and proton cyclotrons, to support radioactive waste management and radiation protection. It presents experimental measurements and Monte Carlo simulations (using codes such as MCNP, GEANT4, FLUKA, PHITS, coupled with CINDER'90 or FISPACT-II) to estimate neutron and photon-induced activation in accelerator components and surrounding materials at energies around 18 MeV. The study compares simulated radionuclide inventories with gamma spectrometry data from a decommissioned medical LINAC and the CYRCé cyclotron facility, highlighting the strengths and discrepancies of different computational tools. Additionally, passive neutron detection using CR-39 solid-state nuclear track detectors complements gamma spectrometry for neutron field characterization, providing valuable data for decommissioning planning and improving activation modeling methodologies.
