In this paper, radiation shielding parameters such as mass attenuation coefficients and half value layer (HVL) of some antioxidants are investigated using MCNPX (version 2.4.0). The validation of the generated MCNPX simulation geometry for antioxidant structures is provided by comparing the results with standard WinXcom data for radiation mass attenuation coefficients of antioxidants. Very good agreement between WİNXCOM and MCNPX was obtained. The results from the validated geometry were used to calculate the shielding parameters of different antioxidants. The radiation attenuation properties of each antioxidant were compared with each other. The results showed that, on average, the highest and the lowest radiation mass attenuation coefficients were observed on hesperidin and delphinidin chloride, respectively. It can be concluded that Monte Carlo simulation is a strong tool and an alternate method where experimental investigations are not possible and a standard simulation setup can be used in further studies for different biological structures. It can also be concluded that the obtained results from this study are very useful for radiology and radiotherapy applications where antioxidants are frequently used.

一些抗氧化剂的辐射屏蔽参数使用蒙特卡罗方法

在本文中，使用MCNPX（版本2.4.0）研究了一些抗氧化剂的质量衰减系数和半值层（HVL）等辐射屏蔽参数。通过将结果与抗氧化剂的辐射质量衰减系数的标准 WinXcom 数据进行比较，可以验证生成的抗氧化剂结构的 MCNPX 模拟几何。WİNXCOM 和 MCNPX 之间获得了非常好的协议。验证几何的结果用于计算不同抗氧化剂的屏蔽参数。将每种抗氧化剂的辐射衰减特性相互比较。结果表明，平均而言，橙皮苷和翠雀素氯化物分别观察到最高和最低的辐射质量衰减系数。可以得出结论，蒙特卡罗模拟是一种强大的工具和替代方法，在无法进行实验研究的情况下，标准模拟设置可用于进一步研究不同的生物结构。还可以得出结论，从这项研究中获得的结果对于经常使用抗氧化剂的放射学和放射治疗应用非常有用。
