摘要

本文旨在利用蒙特卡罗（Monte Carlo）模拟验证和研究0.01 ~ 10 MeV单能量光子在成人人体器官中的相互作用参数。计算肝脏（健康）、肝脏（肝硬化）、肝脏（脂肪）、眼晶体、皮肤、肾脏、心脏（健康）和心脏（脂肪）的质量衰减系数（MAC）、平均自由程（MFP）、半值层（HVL）和第十值层（TVL）。此外，我们还研究了健康肝硬化和脂肪器官对MAC计算的影响。本文采用GAMOS代码MC和理论方法进行计算。将获得的结果与ICRU-46报告发表的结果进行比较。计算结果吻合较好，计算结果的相对误差小于10%。我们已经验证了用于计算单能光子MAC的GAMOS代码。可以得出结论，计算工具在确定任何能量和器官组织的MAC方面是成功和强大的。

Validation and investigation of mass attenuation Coeffcients calculations in different parts of adult human body organ using GAMOS code

This article aims to validate and investigate the interaction parameters of mono-energies photons from 0.01 to 10 MeV in adult human body organs using Monte Carlo (MC) simulation. The Mass Attenuation Coefficients (MAC), Mean Free Path (MFP), Half Value Layer (HVL), and Tenth Value Layer (TVL), of the liver (healthy), liver (cirrhotic), liver (fatty), eye lens, skin, kidney, heart (healthy), and heart (fatty) were calculated. Additionally, we studied the effect of healthy cirrhotic and fatty organs on the MAC calculations. The GAMOS code MC and theoretical Method were used for calculating in this work. The results obtained were compared to those published with the ICRU-46 report. The data showed a good agreement, with a Relative difference in the calculation of less than 10 %. We have validated the GAMOS code for calculating the MAC for mono-energetic photons. It can be concluded that computing tools are successful and powerful in determining the MAC of any energies and organ tissues.

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. 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. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
