Abstract: Neutron imaging is a powerful non-destructive test technique, which is the complement to X-ray imaging. Compared with the lower energy neutrons such as thermal neutron, fast neutron is fit for detecting thinker samples due to having higher penetration. Unfortunately, fast neutron imaging is not paid enough attention to until recent year because of difficult detection. Isotope and accelerator neutron sources are both suitable for developing movable neutron non-invasion detective systems. Especially isotope neutron source has potential of developing handy detective systems. In this paper, the authors describe some of primary results of fast neutron imaging using 241Am-Be neutron source.
