“…The non-destructive character of the neutron radiography and tomography method has prompted the rising interest in studying rare archaeological items and museum rarities, especially metallic artifacts, weapons and ancient jewelry [9][10][11]. It should be emphasized that neutron radiography and tomography have been successfully used to analyze relatively large bronze objects of the Roman period [9], arms from medieval Europe and Japan [10], lead sculptures, and urns [11].…”

Neutron radiography and tomography is a non-destructive method that provides detailed information about the internal structure of cultural heritage objects. The differences in the neutron attenuation coefficients of constituent elements of the studied objects, as well as the application of modern mathematical algorithms to carry out three-dimensional imaging data analysis, allow one to obtain unique information about the spatial distribution of different phases, the presence of internal defects, or the degree of structural degradation inside valuable cultural objects. The results of the neutron studies of several archaeological objects related to different epochs of the Russian history are reported in order to demonstrate the opportunities provided by the neutron tomography method. The obtained 3D structural volume data, as well as the results of the corresponding data analysis, are presented.

“…Thereafter, many research projects were conducted that exploits the unique non-destructive visualization powers of neutrons (complementary with those of X-rays) through digital radiography and tomography to reveal new details about technology of production and state of degradation of objects also for the science of conservation of historical objects [7][8][9][10][11].…”

Aim: Estimating physical stability as well as revealing signs of fabrication in metal artefacts via two complementary non-destructive methods, neutron-and X-ray tomography were the main goals of this study. Abstract:To aid conservation management of metal artefacts improved knowledge of the internal structure and degree of corrosion therein is highly desired. In this study, neutron-and X-ray tomography was chosen as two complementary non invasive visualization techniques to study internal structure and corrosion of five representative examples of archaeological metal artefacts from the Mapungubwe museum collection.Tomography was performed at the Neutron Radiography (SANRAD) facility of the S o u t h A f r i c a n N u c l e a r E n e r g y C o r p o r a t i o n w h e r e t h e r m a l n e u t r o n s a s w e l l a s complementary X-rays are conveniently available under one roof. Comparative studies revealed neutron tomography to be generally superior to X-ray tomography due to the enhanced penetration properties of neutrons through the metal objects. In this paper the rich capability of neutron tomography as a non-destructive visualization aid for scientific conservation purposes is introduced and supported by results achieved for the five selected real artefacts.Keywords: neutron tomography/ X-ray/ archaeological metal/ conservation/ corrosion percentage/ Mapungubwe

“…Tomographic studies can also reveal previous modifications made on the ancient objects or might even reveal forgeries. 5 X-ray tomography is nowadays widely employed in industry, medicine, and material research. 9,10 CT machines are normally built according to the type of application for which they are to be used.…”

“…[1][2][3][4][5][6][7][8] These imaging techniques can yield interesting details about the structure of the objects that can otherwise be detected only through destructive investigations. Once the internal structure is determined, hypotheses about the uses and roles played by the ancient objects in the past can be proposed.…”

X-ray Computed Tomography (CT) is a powerful non-destructive technique that can yield interesting structural information not discernible through visual examination only. This paper presents the results of the CT scans of four objects belonging to the Romanian cultural heritage attributed to the Vinča, Cucuteni and Cruceni-Belegiš cultures. The study was performed with an X-ray tomographic device developed at the Department for Applied Nuclear Physics from Horia Hulubei National Institute for Nuclear Physics and Engineering in Măgurele, Romania. This apparatus was specially designed for archaeometric studies of low-Z artifacts: ceramic, wood, bone. The tomographic investigations revealed the internal configuration of the objects and provided information about the degree to which the previous manipulations affected the archaeological items. Based on the X-ray images resulting from the CT scans, hints about the techniques used in the manufacturing of the artifacts were obtained, as well as some indications useful for conservation/restoration purposes.
