At the International Exhibition of Cultural and Environmental Heritage, being held in Ferrara from today through May 16, ENEA is previewing a reproduction of the head of Pharaoh Ramses II's mummy. The model, made by a laboratory at Sapienza University of Rome for educational purposes, underwent gamma irradiation at the Calliope facility at the ENEA Casaccia Research Center (Rome) to eliminate the microbial communities responsible for the formation of a white patina. The contamination had been caused by direct contact with visitors' hands during previous exhibitions, such as one at the Museum of the Near East, Egypt and the Mediterranean (VOEM). In the coming months, the reproduction of the entire mummy will also be treated. ENEA is also presenting IRIS, an innovative portable laser system for noninvasive diagnostics of cultural heritage. Developed as part of the European E-RIHS project, IRIS enables on-site analysis, without sampling, and with real-time response. The first field test was carried out on the Camponeschi Equestrian Monument in the Basilica of San Giuseppe Artigiano L'Aquila, in collaboration with the Gran Sasso Science Institute, as part of the National Recovery and Resilience Plan project "CHANGES".
