Abstract

The technique of emission tomography employing neutron capture prompt gamma-rays is described. Experiments have been carried out to demonstrate this technique employing a high flux reactor neutron beam using an HPGe detector and a scanning system which incorporates a BBC microcomputer for control, data acquisition, image reconstruction and display. Neutron tomography of the same object was also performed in order to correct the emission tomography results for the neutron flux depression within the sample. The images produced represent the intensity of the induced gamma-ray of interest, and hence the concentration of the isotope of interest.
