NUMISMATIC STUDIES EMPLOY many techniques used in related fields of science. Tomography involves using a penetrating wave to image a section of something. It has been useful in archeology, astrophysics, atmospheric science, biology, geophysics, material science, oceanography, plasma physics, quantum information, radiology, and now numismatics.
Tomography is among the techniques being employed by the Joint Institute for Nuclear Research (Dubna, Russia), Kazan Federal University, and Khalikov Institute of Archeology (Tatarstan Academy of Sciences, Kazan, Russia) as the three organizations study the physical properties of medieval coins found in what had once been the territory of the Volga Bulgar.
The initial results of the study were published May 7 in the paper Studies of Coins of Medieval Volga Bulgaria by Neutron Diffraction and Tomography. The paper presents the chemical and structural…
