Controlling the absorbed dose received by a target is a major challenge encountered during ionizing radiation applications. For experimentally measuring absorbed dose, dosimetric systems are used. On the other hand, in addition to experimental methods of dose measurement, there are other alternatives for calculating absorbed doses, these are numerical methods based on the Monte Carlo method which are very sophisticated and widely used throughout the world. The objective of this work is to demonstrate the effectiveness of Monte Carlo simulation for the contribution to dose control during the dosimetry operation at the Moroccan Boukhalef ionization facility (SIBO). In this study, a comparison is made between Monte Carlo simulation and a dose measurement experiment through the EPR/alanine dosimetry system. This comparison is made in terms of absorbed dose rate in a cylindrical shaped container filled with Expanded Polystyrene (EPS). The results obtained show a good agreement between the Monte simulation and the dose measurement experiment with differences not exceeding 6%. Therefore, Monte Carlo simulation is able to replace or complement experimental methods of dose measurements at the Moroccan Bokhlalef ionization facility.
