Improvement of Neutron Safety Performance of Devices Used in the Prompt Gamma Activation Analysis Technique (PGAA) in Morocco: Modeling and Simulation

This research aims to achieve the desired objectives to install the devices of the prompt gamma activation analysis technique soon. For this, we participated in the realization of models and simulations using the Monte Carlo method to know the behavior and the neutron distribution in the collimator, the sapphire, the shutter (off state), and in the shielding. So we calculated the neutron doses in 10 different positions for the purpose to increase the confidence interval of all radiation leaks.
