For the purpose, we are developing, applying and upgrading the 950 keV/3.95 MeV X-band linac X-ray sources for the on-site inspection. Less than 1 MeV accelerators are available for on-site inspection and less than 3.95 MeV accelerators are allowable for only bridge on-site inspection. These systems can visualize in seconds inner states of infrastructures, such as crack of concrete, iron-reinforced rod/wire and other imperfections. By using the 950 keV system, we conducted the first inspection of the real bridge and evaluated degradation of pre-stressed concrete wires. We also demonstrated first on-site use of the 3.95 MeV system in Japan in 2015. We are also performing structural analysis to evaluate the degradation of strength. For more precise evaluation, we are going to carry out a partial angle CT to reconstruct a two-dimensional inner structure. We are going to present the results and strategy of degradation evaluation of the industrial and societal infrastructures by the 950 keV / 3.95 MeV X-ray sources.
