Abstract

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.

蒙特卡罗模拟在摩洛哥Boukhalef电离设施剂量控制中的有效性评估。

控制目标的吸收剂量是电离辐射应用中遇到的主要挑战。在实验中测量吸收剂量时，使用剂量计系统。另一方面，除了剂量测量的实验方法外，还有其他计算吸收剂量的方法，这些方法是基于蒙特卡罗方法的数值方法，这是非常复杂的，在世界范围内广泛使用。这项工作的目的是证明蒙特卡罗模拟在摩洛哥Boukhalef电离设施（SIBO）剂量测定操作期间对剂量控制的贡献的有效性。本研究通过EPR/丙氨酸剂量测定系统，将蒙特卡罗模拟与剂量测量实验进行对比。这个比较是根据在填充了膨胀聚苯乙烯（EPS）的圆柱形容器中的吸收剂量率进行的。结果表明，Monte模拟与剂量测量实验吻合较好，差异不超过6%。因此，蒙特卡罗模拟能够取代或补充摩洛哥波赫拉莱夫电离设施的剂量测量实验方法。

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
