Abstract

A chemistry module has been implemented in Geant4-DNA since Geant4 version 10.1 to simulate the radiolysis of water after irradiation. It has been used in a number of applications, including the calculation of G-values and early DNA damage, allowing the comparison with experimental data. Since the first version, numerous modifications have been made to the module to improve the computational efficiency and extend the simulation to homogeneous kinetics in bulk solution. With these new developments, new applications have been proposed and released as Geant4 examples, showing how to use chemical processes and models. This work reviews the models implemented and application developments for modeling water radiolysis in Geant4-DNA as reported in the ESA BioRad III Project.

摘要

自 Geant4 版本 10.1 以来，Geant4-DNA 中已经实现了一个化学模块，用于模拟辐照后水的辐射分解。它已在许多应用中得到了应用，包括 G 值和早期 DNA 损伤的计算，允许与实验数据进行比较。自第一个版本以来，已经对该模块进行了多次修改，以提高计算效率并将模拟扩展到体相均相动力学。有了这些新的发展，已经提出了新的应用，并作为 Geant4 示例发布，展示了如何使用化学过程和模型。本工作回顾了在 ESA BioRad III 项目中报告的用于模拟 Geant4-DNA 中水的辐射分解的已实现模型和应用开发。
