摘要
表面去污剂必须能有效捕捉沉积在表面上的颗粒污染物。在涉及核尘埃粒子的情况下,这种能力尤为重要。在本技术说明中,研究了水凝胶(特别是聚乙烯醇-硼砂复合物)作为潜在去污剂处理放射性污染表面的粒子捕获能力。为了进行评估,在不锈钢基底上固定了通过 1200 °C 熔化固结和机械研磨制备的模拟核尘埃粒子。结果表明,水凝胶能有效去除表面的模拟核沉降物颗粒。即使只接触了 1 分钟,表面也被彻底清洁,这证明了聚乙烯醇-硼砂复合物作为表面去污剂的有效性。
Evaluation of particle-capturing ability of a hydrogel-based surface decontamination agent using simulated nuclear fallout particles
Surface decontamination agents must effectively capture particle contaminants that have been deposited on surfaces. This ability is particularly important in scenarios involving nuclear fallout particles. In this technical note, the particle-capturing ability of a hydrogel, specifically, the polyvinyl alcohol-borax complex, was investigated as a potential decontamination agent for treating radioactively contaminated surface. For the assessment, simulated nuclear fallout particles, prepared by melting consolidation at 1200 °C followed by mechanical milling, were fixed on a stainless-steel substrate. The results demonstrated that the hydrogel effectively removed the simulated fallout particles from the surface. Even after only 1 min of contact time, the surface was left thoroughly clean, demonstrating the effectiveness of the polyvinyl alcohol-borax complex as a surface decontamination agent.
