The impact of adding PbO and WO3 on the mechanical properties and radiation shielding efficiency of 4 different glass samples labeled as TWP1, TWP2, TWP3, and TWP4 (samples codes) was studied via the Makishima and Mackenzie model (MMD), Rocherulle model (RD), XCOM database, FLUKA code, and Phys-X/PSD software. According to MMD, Young's (Y), bulk (K), shear (G) modulus values increase from 59.13 to 62.80 GPa, from 37.76 to 43.86 GPa, from 25.48 to 26.55 GPa, and from 71.73 to 79.26 GPa for TWP1 and TWP4 glasses, respectively. 277.833, 358.768, 465.048 and 570.786 cm-1 values are the highest linear attenuation coefficient (μ) values for TWP1, TWP2, TWP3 and TWP4 glasses at 0.015 MeV. The results refer that the TWP4 glass sample has the highest radiation shielding and mechanical properties. The results indicated that the addition of lead and tungsten to the investigated samples improves their elastic and radiation shielding properties. Thus, the TWP4 sample is the best compared to the other glass samples.

重元素对某些碲酸盐玻璃电离辐射屏蔽效率和弹性的影响:理论研究

加入PbO和WO的影响3上的标记为TWP1,TWP2,TWP3,和TWP4(样本代码)4个不同的玻璃样品的机械性能和辐射屏蔽效率经由卷岛和Mackenzie模型(MMD),Rocherulle模型(研究RD),XCOM数据库,FLUKA代码和Phys-X / PSD软件。根据MMD,对于TWP1和TWP4眼镜,杨氏(Y),体积(K),剪切(G)模量值从59.13 GPa增加到62.80 GPa,从37.76 GPa增加到43.86 GPa,从25.48 GPa增加到26.55 GPa,从71.73 GPa增加到79.26 GPa。 , 分别。277.833、358.768、465.048和570.786 cm -1值是0.015 MeV时TWP1,TWP2,TWP3和TWP4眼镜的最高线性衰减系数(μ)值。结果表明,TWP4玻璃样品具有最高的辐射屏蔽和机械性能。结果表明,所研究的样品中添加铅和钨可改善其弹性和辐射屏蔽性能。因此,与其他玻璃样品相比,TWP4样品是最好的。
