Abstract
Reconstructive tomography was carried out using multiple neutron radiographs of an object as well as multiple projections of the transmitted neutron beam through the object using an He-3 proportional counter. Gamma-ray transmission tomography employing the 60 keV gamma-ray line of a well-collimated Am-241 source was also applied to the same object.
A 35mm camera was modified to incorporate a neutron converter so that sequential radiographs could be obtained without disturbing the geometrical arrangement between beam, object and recording medium. A conventional converter/film combination, in one single cassette, was also used. Results show that the technique using the collimated He-3 neutron detector provides tomographic images which are superior in terms of contrast and noise due to statistical fluctuation.
