“…It is accepted [4] that neutron attenuation processes are described by total scattering cross-sections as the sum of neutron scattering and absorption cross-sections, or by the attenuation length. The spatial resolution capabilities of the neutron tomography facility impose some restrictions on the minimum size of a resolved item, up to 270 microns or 0.02 mm 3 .…”

“…It is desirable to investigate them by modern non-destructive methods [2]. One of the non-destructive methods is X-ray tomography, which makes it possible to obtain three-dimensional (3D) visual data with a good precision for use both in qualitative and quantitative studies [3]. However, X-ray tomography methods, including those applied using synchrotron radiation sources, have some restrictions with respect to the dimensions of the objects under study, and the worsening of the imaging data due to X-ray attenuation by metals, resulting in beam hardening.…”

“…Thus, there are limits on the sample sizes that can be examined. A complementary method to X-ray tomography is neutron radiography and tomography [3][4][5][6]. The fundamental difference in the nature of neutron interactions with matter compared to X-rays provides additional benefits to neutron methods, including sensitivity to light elements, a notable difference in contrast between different metals, and high penetration ability.…”

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.

This entry gives an introductory overview of the application of the modern well‐established neutron and X‐ray imaging methods to museum objects and related materials. Since both kinds of radiation complement each other often in their interaction with matter, a combination of the image data can provide the perfect noninvasive picture of inner contents and structures. In the framework of this entry, we can only show some principles and examples from studies, while details are referenced and given in the literature. More advanced techniques are under development and will be implemented into the routine work on demand. We mention them here for completeness.

Public interest in archaeology has increased dramatically in recent years. Scientific studies of archaeological objects have answered and generated detailed questions as to the origins, dating, material composition, and ancient methods of fabrication. All of these results have impacted our developing understanding of culture and heritage. Three‐dimensional computed tomography (3D CT) can provide unrivalled inspections of the structure and details of objects and assemblies. While some objects fall within the effective energy range of medical scanners, many metal objects or larger objects require energies that are beyond the restricted range of medical CT. Further, it is frequently impossible to move objects of archaeological interest to diagnostic laboratories, which encourages the development of transportable 3D CT systems. This essay provides a brief overview of the uses of 3D CT (using X‐rays, gamma‐rays or neutrons) for addressing the current questions posed by archaeologists.
