Abstract

The transmission of photons through a target produces 'holes' in the transmitted energy spectrum that are characteristic of the NRF energies of the nuclear isotopes in the target. Measuring the absorption via the transmission of these photons through a target allows the production of tomographic images that are associated with specific nuclear isotopes. Thus three-dimensional density patterns are generated for the elements in a container. The process is very much like standard X-ray tomography but it identifies specific nuclear isotopes as well as their densities.
