摘要
我们利用极性溶剂中的溶解离子制造出了透明、无铅的 X 射线屏蔽材料。以前的材料都是基于含金属颗粒（如硫酸钡 (BaSO4)）在基质中的分散体。通过比较金属基颗粒悬浮液和金属离子在溶剂中的溶液，可以更好地了解 X 射线与物质之间的相互作用，如反射、散射和吸收。溶解金属离子溶液的 X 射线屏蔽性能类似于或优于含金属颗粒的悬浮液。此外，金属离子溶液还具有很高的透明度。在所研究的材料中，最有效的 X 射线屏蔽材料是溴化钡（BaBr2），它在极性溶剂中具有很高的溶解度。在管电压为 120 kV 时，X 射线屏蔽率为 92%，在可见光波长为 400 nm 时，紫外线透过率为 90%。因此，既实现了高 X 射线屏蔽性能，又实现了高透明度。
Transparent X-ray Shielding Solutions with Various Metal Ions
We fabricated transparent, Pb-free X-ray shielding materials using solvated ions in a polar solvent. Previous materials have been based on dispersions of metal-containing particles such as barium sulfate (BaSO4) in a matrix. Comparisons of suspensions of metal-based particles and solutions of metal ions in a solvent enable better understanding of interactions such as reflection, scattering, and absorption between X-rays and substances. The X-ray shielding properties of a solution of solvated metal ions were similar to or better than those of suspensions of metal-containing particles. In addition, the metal-ion solutions exhibited high transparency. The most effective material among those investigated for X-ray shielding was barium bromide (BaBr2), which exhibits high solubility in polar solvents. X-ray shielding of 92% was confirmed at a tube voltage of 120 kV, along with ∼90% UV transmittance at a visible-light wavelength of 400 nm. Thus, both high X-ray shielding performance and high transparency were achieved.
