A neutron radiography is technology which carries out visualization and measurement of the inside of a substance using neutrons. This technology has the complementary feature comparing with X-ray radiography (Roentgen technique). In this review paper, the measurement principle, some application examples such as visualization of oil in the working car engine, and about the leading-edge technology using high-intensity proton beam accelerator facility J-PARC (common neutron imaging facility), etc. It was introduced in the form where the whole neutron radiography technology for every dimension of measurement were covered.

The fundamentals and applications on the neutron imaging technique, volume visualization and 3D measurement by the neutron 3D-CT technique and the most advanced imaging technique by using pulsed neutrons were reviewed in this paper. Visualization and measurement of the inside mortaring car engine is one of the industrial applications on the neutron imaging technique. This technique was also applied for visualization and measurement of the multiphase plow applications. The 3D visualization technique has been used for the concrete research etc. The pulsed neutron imaging techniques developed for J-PARC have made possible element-selective imaging and metallographic structure imaging which were impossible by the traditional techniques. Newly providing pulsed neutron imaging facilities for common use is also introduced briefly.

By means of in-situ high-temperature and high-pressure experiment, we found two distinct structures of molten phosphorus, one is a molecular fluid and the other is a polymeric liquid, and an abrupt and reversible structural transformation between them at about 1 GPa. Further investigations revealed that the two structures have different densities and they separate macroscopically during the transformation. These results support a view that this change is an extremely rare example of a first-order phase transition between two stable disordered phases besides liquid-gas transition.

In this study, it was conducted to evaluate the long-term adhesion characteristics of post-installed anchors using neutrons, which have extremely high penetrating power for materials. In CT measurement, it was clarified that the observation inside the reinforced concrete of about 60 mm can be evaluated with the spatial resolution of about 0.2 mm. On the other hand, since the strain distribution under loading did not show a monotonous change in the strain distribution of the anchor, it was clarified that there are some problems.
