Paper Abstract

We describe a method of reconstructing the volume, and of estimating the lower bound of the density, of objects absorbing radiation by resonant (gamma-proton) reactions. The method is easily adapted to conical beams. The advantages of the imaging method to the detection of explosives in laboratory system based on nuclear resonance absorption are examined. The results of applying the method to the inspection of nitrogenous objects are presented, including the usefulness of oversampling and the relative success of differentiating explosives from innocuous materials based on nitrogen densities.
