摘要
电离辐射需要屏蔽,以防止或减轻由此产生的辐射风险。低 Z 材料(如聚乙烯)适用于中子屏蔽,而高 Z 材料(如铅)适用于光子(伽马射线和 X 射线)。混凝土是一种传统的屏蔽材料,可用于屏蔽光子或中子。虽然混凝土价格低廉且易于成型,但其排放的二氧化碳却占总排放量的 8%。如果火山硅石(VSR)能替代混凝土起到屏蔽辐射的作用,这将有助于减少二氧化碳的排放量。蒙地卡罗代码 Fluka 被用来模拟实验设置,并计算屏蔽样品另一侧的辐照率。结果表明,VSR 的线性系数、质量衰减系数和吸收系数几乎与混凝土相同。这些结果表明,VSR 可以与混凝土类似,用于屏蔽高达 250 keV 的 X 射线诊断范围。
The Promising Use of Volcanic Silica Rocks as an Environmental Source for Diagnostic X-ray Shielding Applications
Ionizing radiation shielding is required to prevent or mitigate the radiological risks resulting therefrom. Low Z materials such as polyethylene are preferable for neutron shielding, while high Z materials such as lead are preferable for photons (gamma and x-rays). Concrete is a conventional shielding material that is used to shield against either photons or neutrons. Although concrete is cheap and can be easily formed, it is responsible for 8% of carbon dioxide emissions. If volcanic silica rocks (VSR) take the role of concrete in radiation shielding, this will help reduce the level of carbon dioxide emission. Monte Carlo code Fluka was used to simulate the experiment setup and calculate the exposure rate on the other side of the shielding samples. The obtained results showed that the linear, mass attenuation, and absorption coefficients of the VSR are almost like those of concrete. These results reveal that the VSR could be used similarly to concrete for the shield against X-rays diagnostic range up to 250 keV.
