Abstract

The efficacy for radiological decontamination of the laboratory standard fume hood as constructed of stainless steel, compared to that of powder-coated carbon steel is described. While the chemical inertness of powder-coated surfaces is good, faced with everyday abrasion, aggressive inorganic solutions and vapors, and penetrating organics commonly employed in government laboratory fume hoods, radiological decontamination of powder-coated steel surfaces was found to be similar to those made of stainless steel for easily solubilized or digestible radionuclides. Plutonium was difficult to remove from stainless steel and powder-coated surfaces, especially after prolonged contact times.

摘要

描述了由不锈钢制成的实验室标准通风柜与粉末涂层碳钢制成的通风柜在放射性去污方面的效果。虽然粉末涂层表面具有良好的化学惰性，但在面临日常磨损、腐蚀性无机溶液和蒸气以及政府实验室通风柜中常用的渗透有机物时，发现粉末涂层钢表面的放射性去污效果与不锈钢相似，对于易于溶解或可消化的放射性核素而言。钚很难从不锈钢和粉末涂层表面去除，特别是在长时间接触后。
