Abstract
A large-scale neutron imaging method using fast neutrons of over 1 MeV is being developed for nondestructive inspection of infrastructure. Development of compact neutron source and large area fast neutron detector in RIKEN is discussed. Different number of the steel bars, voids, and existence of water in 30 cm thick concrete are clearly observed.
