Combination of neutronography and radiography for the characterizing of light material distribution in a dense material matrix

Neutronography and radiography are complementary methods from the point of view of the visibility and contrast of the material imaged. Neutronography is the suitable tool for the observation of light material penetration into a dense material matrix. However, dense materials are difficult to observe using neutronography. X-ray radiography appears complementary as an appropriate tool to determine the connection between light material deposition and matrix structure. The methodology used can be applied also for engineering tasks such as the distribution of hydrogen in steel, resin damages in metal-glass epoxy composites and so on.
