Abstract

This study aims to evaluate different photon interaction parameters of human body organs at nine photon energies (0.021 keV–1.25 MeV) using GAMOS and FLUKA Monte Carlo codes. The Mass attenuation coefficients, Mean Free Path, Half Value Layer, Tenth Value Layer, and Mass absorption coefficients of the breast, lung, kidney, pancreas, liver, eye lens, thyroid, brain, ovary, heart, large intestine blood, skin, spleen, muscle, and cortical bone were investigated and compared against the standard values available from the tables of XCOM database. This comparison demonstrated a good agreement, with all calculated values deviating less than 6 %. In addition, the values obtained with the GAMOS code were similar to those obtained using the FLUKA code. These comparisons indicate very good agreement and revealed that both FLUKA and GAMOS codes can be used as a computational tool for determining the photon interaction parameters of any material and also different energies, whose data are not available in the literature.

利用 GAMOS、FLUKA 和 XCOM 研究调查人体组织中的光子相互作用参数

本研究旨在使用 GAMOS 和 FLUKA 蒙特卡洛代码评估人体器官在九种光子能量（0.021 keV-1.25 MeV）下的不同光子相互作用参数。研究了乳腺、肺、肾、胰腺、肝、眼晶状体、甲状腺、脑、卵巢、心脏、大肠血液、皮肤、脾脏、肌肉和皮质骨的质量衰减系数、平均自由路径、半值层、十值层和质量吸收系数，并与 XCOM 数据库表格中的标准值进行了比较。比较结果表明，所有计算值的偏差均小于 6%，一致性良好。此外，使用 GAMOS 代码获得的值与使用 FLUKA 代码获得的值相似。这些比较结果表明两者的一致性非常好，并揭示出 FLUKA 和 GAMOS 代码都可以作为一种计算工具，用于确定任何材料的光子相互作用参数以及不同能量的光子相互作用参数，而这些参数的数据在文献中是没有的。
