Neutron-imaging (NI) has been established as a non-destructive technique which can be applied from
fundamental research to industry. In particular, radiography results in a two-dimensional image of the sample
studied and, if time resolved, can visualize dynamic processes. Tomography provides three-dimensional
information through a reconstruction of macroscopic cross sections of the object under investigation. As attenuation coefficients differ from X-ray to neutron for the same element, NI can produce complementary data.
Whereas X-rays are more suitable to investigate dense materials inside light ones, neutrons are able to detect light elements such as hydrogen, carbon, and nitrogen, embedded into metallic or ceramic objects. Additionally, the
high penetration depth of neutrons allows studying large samples of some materials, with volumes of up to 100
cm3 at medium resolutions. These unique properties have raise interest in the application of NI in different fields
of scientific research; i.e. the visualisation of fluid uptake and flow in natural building stones and sedimentary
rocks, quality control on pyrotechnic devices like detonators, the characterization of ancient manufacturing
techniques from Museum objects, etc. Recently, a neutron imaging beam-line DINGO has become operative at
the Australian neutron research facility based on the OPAL research reactor at ANSTO (Lucas Height)). Classical
applications of neutron imaging conducted at international facilities will be shown and results from samples investigated on DINGO will be presented.
