摘要
摘要在牙科科学中，提取是很重要的，因为它既用于诊断，也用于治疗问题。由于食物和刷牙残留的硬颗粒，甚至由于与其他牙齿的接触，牙齿每天都暴露在大量的磨损中。牙齿修复被广泛用于矫正这种磨损造成的损害。在本研究中，旨在确定剂量学材料羟基磷灰石(HAP)和氨基丙烯酸酯(UDMAs)的辐射屏蔽性能。采用GAMOS (Geant4-based Architecture for Medicine-Oriented Simulations)蒙特卡罗仿真程序计算剂量学材料的线性衰减系数。并将所得结果与XCOM计算结果进行了比较。得到了平均自由程(mfp)、半值长度(HVL)和十分值长度(TVL)。S2样品在511、662、835、1173、1275和1332 keV能量时LAC值最高(分别为0.170、0.149、0.133、0.112、0.108和0.105 cm−1)，S3样品在511、662、835、1173、1275和1332 keV能量时LAC值最低(分别为0.102、0.091、0.082、0.069、0.066和0.065 cm−1)。
Gamma-ray shielding properties of some dosimetric materials
Abstract
Radiation is important in dental science as it is used in both diagnostic and also in treatment issues. The teeth are every single day exposed to a significant amount of wear due to remaining hard particles from food and tooth brushing or even due to the contact with the other teeth. Dental restorations are widely used to correct the damage caused by this wear. In this study, it is aimed to determine the radiation shielding properties of the dosimetric materials which are namely hydroxyapatite (HAP) and urethane di(meth)acrylates (UDMAs). The linear attenuation coefficients of dosimetric materials were calculated using GAMOS (Geant4-based Architecture for Medicine-Oriented Simulations) Monte Carlo simulation code. The obtained results were also compared with the calculation done using XCOM. The mean free path (mfp), half value length (HVL), and tenth value length (TVL) have also been obtained. The highest LAC value was obtained for S2 sample for 511, 662, 835, 1173, 1275, and 1332 keV energies (0.170, 0.149, 0.133, 0.112, 0.108, and 0.105 cm−1, respectively) and the lowest LAC values were obtained for S3 sample for 511, 662, 835, 1173, 1275, and 1332 keV gamma energies (0.102, 0.091, 0.082, 0.069, 0.066, and 0.065 cm−1, respectively).
