neutron radiography [′nü‚trän ‚rād·ē′äg·rə·fē] (nucleonics) Radiography that uses a neutron beam generated by a nuclear reactor; the neutrons are detected by placing a conventional x-ray film next to a converter screen composed of potentially radioactive materials or prompt emission materials which convert the neutron radiation to other types of radiation more easily detected by the film.

| Researchers from NIST, the University of Melbourne, and the University of Missouri at Columbia have demonstrated a new form of neutron radiography that produces greatly enhanced images of fine structural details in test samples with relatively low levels of radiation. For instance, while the facility performs neutron radiography for NASA and local automakers -- such as imaging where carbon deposits build up in a car's fuel injectors -- Burn says, "we only provide such unique services when you can't get them any other way. This technique is different from conventional neutron radiography where only the bulk features of a sample are visualized. |
