The Use of Isotopic Neutron Sources for some Radionuclides Production in Nuclear Medicine and other Domains of Science

摘要

Introduction: The radioisotopes production can be performed through different nuclear reactions, which could take place in nuclear reactors or in accelerators. The method of obtaining radioisotopes through a mechanism of irradiation with neutrons consists of bombarding some elements with different energy neutrons [1, 2, 3]. The neutrons obtained from isotopic neutron sources of (a , n) type were used in this paper. These neutron beams provided by these sources, were obtained from nuclear reactions initiated by the radioisotopic constituents. The neutrons spectrum shows a continuous energetic distribution of two main peaks at energies of 3.2 and 5.1 MeV. These fast neutrons were thermalized in paraffin.
