Abstract
Isotope identification imaging of nuclear fuel material or explosives concealed in a drum or container in which nuclear reactor fuel or radioactive waste are sealed is realized while ensuring high precision, high reliability, and safety. A sampleis irradiated with laser Compton photon beamsandgenerated by a collision between an electron beamand polarized laser lightand. An isotope in the sample is identified using nuclear resonance fluorescence, and the spatial distribution thereof is imaged. In so doing, a nuclear level of an isotope whose emission direction of nuclear resonance fluorescence is dependent on the planes of polarization of the incident LCS photon beams is used.
