摘要：

Simultaneous use of a number of radioactive tracers affords not only efficient acquisition of data on various elements but also precise determination of the characteristic behavior of different elements under identical experimental conditions. The advance in solid-state detectors, counting circuits, and computers has made possible the measurement and analysis of complex gamma-ray spectra of samples containing a number of radioactive nuclides. The RIKEN Ring Cyclotron can accelerate heavy ions up to 135 MeV/nucleon. The nuclear reactions induced by heavy ions of such energy result in simultaneous production of a large number of radioactive nuclides. We developed a convenient and reliable radiochemical procedure by which to prepare radioactive multitracer solutions free from both carriers and salts by using Au, Ag, and Cu targets irradiated with a C-12, N-14, or O-16 beam. The preparative method of the multitracer solution from the Au target has been briefly reported [1].
