PREPARATION OF RADIOACTIVE MULTITRACER SOLUTIONS FROM Au, Ag, AND Cu FOILS IRRADIATED WITH HIGH-ENERGY HEAVY IONS

Abstract

Au, Ag, and Cu foils were irradiated with high-energy heavy ions accelerated by the RIKEN Ring Cyclotron. Each foil was dissolved in aqua regia or nitric acid. The target materials, Au, Ag, and Cu, were precipitated as metallic Au, AgCl, and CuSCN, respectively, and filtered out to yield carrier- and salt-free multitracer solutions containing a large number of radioactive nuclides.
