Neutron resonance absorption spectroscopy (N-RAS) using a pulsed neutron source can be applied to time-of-flight (TOF) radiography analysis can be reconstructed as the tomograms of nuclide distributions using computed tomography (CT). The problem is that the available spatial resolution is not sufficient for radiography imaging. In this study, we combined the neutron and gamma-ray (X-ray) radiography, which utilize the gamma-rays (or X-rays) at the same time as the neutron pulse is emitted, to improve the spatial resolution of the quantitative reconstruction of the neutron tomogram. And, we applied the neutron image intensifier with the shutter function to the Bragg edge radiography of material distribution.
