摘　　要：采用γ射线对纸张(模拟纸质文献档案)样品进行辐照,考察杀虫灭菌效果。分析辐照后纸张的力学性能和图案字迹颜色等,优化辐照最佳吸收剂量。结果表明:吸收剂量为2 kGy时,曲霉菌、枯草芽孢杆菌、烟草甲和毛衣鱼杀灭率可达99.9%以上;老化后样品的纸张力学性能、装订物、墨迹均至少保持在原样品性能的80%,不会对后期的保藏产生不良影响。综合考虑杀虫灭菌的有效性,纸质文献档案的安全性,以及辐照服务的经济性,用于纸质文献档案保藏的吸收剂量控制在2 kGy较为合适。In this study,the optimal dose of irradiation for insecticidal sterilization was investigated by simulating different doses ofγrays irradiation on paper samples(simulated paper document archives),and the mechanical properties of paper,colors of patterns and handwriting were analyzed.In case of Aspergillus,Bacillus subtilis,tobacco beetle,and ctenolepisma villosa,the killing rate>99.9%was achieved when the absorbed dose was 2 kGy.After aging,the mechanical properties,gutters and ink marks of the samples were kept at least 80%of the original ones,which would not affect the later preservation.In consideration of the effectiveness of insecticidal sterilization,safety of paper document archives,and economics of irradiation services,the absorbed dose of 2 kGy was appropriate for the preservation of document archives.
