电离辐射防护用纺织品的研究进展

Research Study of Ionizing Radiation Protective Textiles

总结电离辐射防护用纺织品的研究进展。阐述了电离辐射的概念、特点及危害;对比了国内外电离辐射防护方面所执行标准的异同;重点介绍了电离辐射防护用纺织品种类、制备工艺、防护性能及不同应用场景要求上的差异等,并展望了电离辐射防护技术及产品研发方向。认为:电离辐射中X射线和低能γ射线是纺织品所需要防护的重点;采用金属合金材料、金属粉末共混以及多层结构材料将是实现较宽能量射线较好防护的有效手段。

The research progress of ionizing radiation protective textiles was summarized.The concept,charac⁃teristics and harm of ionizing radiation were explained.The differences and similarities of standards that were fol⁃lowed in the filed of ionizing radiation protection at home and abroad were compared.The categories of textiles for ionizing radiation protection,preparation processing,protective properties and the differences for different application scenarios and so on were emphatically introduced.The protective technology of ionizing radiation and the product de⁃velopment direction were looked ahead.It is considered that X-ray of ionizing radiation and lower energyγ-ray are the key to protect for the textiles.Adapting metal alloy materials,blended metal powder andmaterials with multiple structure are the efficient measures to achieve better protection on wider energy ray.
