Gamma irradiation technologies Cultural heritage conservation and characterization procedures before and after radiation exposure
The proposed technology involves the controlled application of gamma radiation for the disinfection and pest control of cultural heritage objects made from organic and inorganic materials (paper, parchment, wood, stone, textiles, etc.). This method, already validated internationally, provides a sustainable and non-invasive alternative to traditional chemical-based approaches. The innovation lies in promoting a scientifically validated protocol tailored to the Italian context, where the technique remains underutilized.
Application sectors
Problem to solve
This proposal aims to address the limitations of traditional disinfection and pest control methods for cultural heritage objects, which often rely on toxic chemicals that pose health risks to operators and may harm the materials themselves. Such methods can leave residues and require long treatment times. Gamma radiation provides an effective, fast, and non-invasive alternative that, when properly applied, eliminates biological threats without altering the physical or chemical properties of the artifacts.
Description
This proposal aims to systematically introduce the use of gamma radiation in the conservation of cultural heritage in Italy. Unlike traditional chemical methods, which are often toxic and invasive, gamma irradiation eliminates biodeteriogenic agents without altering the structure of the treated materials. The process is fast, residue-free, and fully compatible with restoration activities. The innovation lies in the adoption of standardized protocols and the integration of pre- and post-irradiation characterization procedures to ensure the treatment's effectiveness and safety.
