Abstract

The fundamentals, experimental possibilities, and applications of the methods of neutron radiography and tomography in studies of the structural features of large objects in various fields are reviewed. The main principles of neutron imaging are considered. Specialized experimental stations at the National Research Centre “Kurchatov Institute” and the Joint Institute for Nuclear Research are described, and their main parameters are presented. The experimental capabilities of these neutron facilities, including methodological approaches to variation of the neutron radiographic contrast with neutron energy dispersion, are described. A detailed review of the scientific results obtained on neutron radiography and tomography facilities is presented; these results concern engineering and technological objects, internal structure of meteorites, paleontological samples, and cultural heritage objects.
