Abstract

Abstract This work describes mass recovery processes of flooded archival materials at industrial scale. The presence of fungi on paper represents a threat to the integrity of the document because they degrade cellulose, one of the main components of paper. Gamma radiation treatments are investigated as mass disinfection agents for their high penetrating power, speed of treatment, and absence of risk due to chemical residuals. We compared two different recovery processes: thermal drying followed by gamma irradiation and gamma irradiation followed by thermal drying. Both these processes were conducted simultaneously on naturally contaminated archival items and on paper specimens artificially contaminated with test species. Efficacy was assessed by culture method and ATP assay, right after the treatments and after four years of storage at room temperature. Coupling gamma irradiation with a drying step with dry heat at 55–60 °C reduces the fungal loads on natural items up to levels close to the detection limits, and the reduction is maintained after four years. On artificial specimens, spore germination is completely inhibited, mycelia growth is also highly affected, but the melanised test species appear to be more resistant. A synergistic effect between gamma irradiation, water content, and thermal drying is highlighted in this paper.

伽玛辐射对淹没档案材料的大规模处理
摘要这项工作描述了在工业规模上被淹没的档案材料的大规模回收过程。纸张上真菌的存在对文件的完整性构成威胁,因为它们会降解纸张的主要成分之一纤维素。伽马辐射治疗被研究为大规模消毒剂,因为它们具有高穿透力、治疗速度和不存在化学残留物造成的风险。我们比较了两种不同的回收工艺:热干燥后进行伽马辐射和伽马辐射后进行热干燥。这两个过程都是在自然污染的档案物品和被测试物种人工污染的纸张样本上同时进行的。在处理后以及在室温下储存四年后,通过培养方法和ATP测定来评估疗效。将伽马辐射与55–60°C的干热干燥步骤相结合,可以将自然物品上的真菌负荷降低到接近检测极限的水平,并且在四年后保持这种减少。在人工标本上,孢子发芽被完全抑制,菌丝生长也受到很大影响,但黑化的试验物种似乎更具抵抗力。本文强调了伽马辐射、含水量和热干燥之间的协同效应。

期刊介绍: Restaurator is the only international periodical specializing exclusively in the conservation of library and archive materials. Articles examine the many important aspects of this subject area, such as technology, practical experience and organization. They also focus on scientific basics: Many articles deal with the development of new preservation techniques and the improvement and better understanding of established methods. The articles are written in English with summaries in English, French and German. By reading Restaurator regularly, librarians, archivists and restorers can keep up to date with the latest research and developments. The editorial committee is made up of experts from well-known institutions and organizations from all over the world
