Each NDT method has its own set of advantages and disadvantages and, therefore, some are better suited than others for a particular application.

Nondestructive testing (NDT) is the process of inspecting materials, components and assemblies in order to find discontinuities or differences in their characteristics without damaging the particular system.

The crystal structure determined by X-ray diffraction is a periodic structure which is repeated according to atoms in the crystal.

Radiography can be applied to nuclear industrial devices, explosive devices, turbine blades, electronics, and aerospace structural components (including metal honeycomb structures and components).

The ability to "see through" a solid object was once thought to be a tool of the future, or a power belonging to Superman–but the technology is here today

The neutrons emitted by most neutron sources need to be slowed down by the reducer to become thermal neutrons, and then the collimator is used to limit the emission angle of the neutron beam, making it called beam irradiation.
