Abstract

Gamma irradiation technology plays a very important role in the development of agriculture, due to its various advantages, such as the inhibition of germination, the appearance of new varieties, preservation…etc. To properly control and characterize irradiation operations, the dose rate distribution in the irradiation cells must be well controlled, The Monte-Carlo method was used for experiments the high cost to map the dose rate distribution in the irradiation cell each time, and to its precise dosimetric calculation. In this study the MCNPX code was used to simulate the irradiation cell of the National Institute of Agricultural Research (NIAR) of Tangier Morocco, the validation of the latter was based on a comparative assessment between the dose rates absorbed in the area calculated by MCNPX (Gy/min) and those measured values by alanine dosimeters. The comparative results showed a good agreement between the experiment and the simulation.

使用MCNPX代码对摩洛哥全景伽玛辐照器剂量率分布进行的蒙特卡洛模拟

摘要

伽马辐照技术由于具有多种优点，例如抑制发芽，出现新品种，保存等，在农业发展中起着非常重要的作用。为了适当地控制和表征辐照操作，必须很好地控制辐照池中的剂量率分布。使用蒙特卡洛方法进行实验，每次绘制映射在辐照池中的剂量率分布及其精确的高成本剂量计算。在这项研究中，MCNPX代码用于模拟丹吉尔摩洛哥国家农业科学研究所（NIAR）的辐照室，后者的验证是基于对MCNPX计算的面积吸收剂量率（Gy / min）和丙氨酸剂量计测得的剂量率之间的比较评估。对比结果表明，实验与仿真结果吻合良好。
