摘要

为使工业60Co γ辐照装置更好地应用于抗辐射加固研究，应用蒙特卡洛程序GEANT4模拟计算了辐照空间的剂量率分布，并搭建了基于ROOT程序的数据在线存储及离线处理平台。通过合理设计模拟过程，使得模拟结果的统计误差<5%。同时，建立了剂量率分布的计算模型，并利用重铬酸银剂量计完成了实验验证。GEANT4模拟、模型计算以及实验测量三者结果相符合，且模拟与实验的相对偏差<5%。这表明模拟过程正确描述了辐照空间的剂量率分布，所搭建的模拟和数据处理平台可用于相关实验的开展。

Abstract

A detailed GEANT4 Monte Carlo study was performed to calculate the dose rate distributions of an industrial 60Co γ-rays irradiation facility, so it could provide a better service for the research of radiation hardening. All data produced during simulations were on-line stored and off-line analyzed by ROOT. With careful design of simulation processes, the relative errors were less than 5%. For the validation purpose, experiments with ferrous sulfate dosimeter were carried out. Furthermore, a computational model was constructed as a comparison. The relative deviations between simulated and experimental results were less than 5%. The satisfactory agreement of simulations between model and measurements indicates that our work has designed the processes of simulation and got the dose rate distributions in a correct way.Cited
