Neutron radiography (NR) is a non-destructive inspection and testing technique capable of producing images of components, assemblies and materials, on film or real time devices, using neutrons as the penetrating medium. In comparison to X- and gamma-rays, neutrons penetrate heavy metals such as steel, lead or uranium much more easily, whilst at the same time having the unique capability to image light materials such as hydrogen-bearing materials or tracer materials such as cadmium, gadolinium and dysprosium. NR services for nuclear and non-nuclear applications are mainly provided by test reactor-based systems at various research institutes and organisations in the European Community member states.
