Secure detection of nuclear material in a heavy shielding and reliable investigation of inner structure of the shielding using mono-energetic high energy and high intensity -rays

Hajima, Ryoichi; Seya, Michio

Monochromatic -rays produced by laser Compton scattering could be used for detection of nuclear material with cobined use of nuclear resonance flourescence. By using ERL (Energy Recovery Linac) based -ray source for producing high intensity, it is possible to detect nuclear material inside an heavily shielded object and also to have clear imaging inside of it. In this poster presentation, a prospect of application of the -ray source to nuclear material detection system.
