Safety of non-invasive surveys using radiation of specific wavelength
Summary: This article presents the results of safety measurements of a non‑invasive survey using radiation of specific wavelength. The research was carried out within the framework of the NAKI II project DG18P02OVV024 entitled „Use of imaging methods for the study of hidden information in books“. The paper presents the studied sources of radiation used for non‑invasive imaging of hidden information, the effect of radiation on book binding materials and documents, and especially the specific results of measurements of the effect of selected methods on the change of visual, chemical and mechanical properties of paper and collagen materials.
