Resonant photonuclear isotope detection using medium-energy photon beam

Nuclear Science, Czech Technical University, Prague, Czech Republic(Received 9 November 2011; published 2 February 2012)Resonant photonuclear isotope detection (RPID) is a nondestructive detection/assay of nuclear isotopesby measuring rays following photonuclear reaction products. Medium-energy wideband photons ofE ¼ 12–16 MeV are used for the photonuclear ð;n Þ reactions and rays characteristic of the reactionproducts are measured by means of high-sensitivity Ge detectors. Impurities of stable and radioactiveisotopes of the orders of gr—ngr and ppm—ppb are investigated. RPID is used to study nuclear isotopesof astronuclear and particle physics interests and those of geological and historical interests. It is used toidentify radioactive isotopes of fission products as well.
