N-radiography is an excellent tool for non-destructive
inspection of electronic, mechanical and ordnance parts
and assemblies for:
Residual core material
Gaps, voids, foreign material, density variations or
misalignment of explosives or other hydrogenous materials
surrounded by metal
Epoxy or potting voids
Missing or misplaced O-rings
Hydrogenous foreign substances in sealed units
Small internal cracks
Delaminations
Distribution of neutron poisons (e.g. boron, cadmium, hafnium,
etc.) in materials
Adhesive bonding flaws
Blockages in small ECM, EDM, or laser formed channels
N-radiography is also used for R & D, detection of the limit of
hydriding in materials, pre-disassembly failure analyses,
and others.
