The production, diffusion, and interaction of particle beam induced water-derived radicals is studied with the a pre-chemical and chemical module of the Monte Carlo particle track structure code TRAX, based on a step by step approach. After a description of the model implemented, the chemical evolution of the most important products of water radiolysis is studied for electron, proton, helium, and carbon ion radiation at different energies. The validity of the model is verified by comparing the calculated time and LET dependent yield with experimental data from literature and other simulation approaches.

TRAX-CHEM：水目标中粒子轨道结构代码TRAX的化学前和化学阶段扩展

基于逐步方法，使用蒙特卡洛粒子轨道结构代码TRAX的化学前和化学模块研究了粒子束诱导的水衍生基团的产生，扩散和相互作用。在描述了所实施的模型之后，研究了水辐射分解最重要产物的化学演化，研究了不同能量下的电子，质子，氦气和碳离子辐射。通过将计算的时间和LET依赖的产量与来自文献和其他模拟方法的实验数据进行比较，验证了模型的有效性。
