Fission neutron spectrum averaged cross sections of some threshold reactions on cadmium: production feasibility of no-carrier-added ¹⁰³Pd in a nuclear reactor

Keywords: Fission neutron spectrum, Neutron threshold reaction, Activation technique, Cross section, Radiochemical separation

Systematic studies on fission neutron spectrum averaged cross sections of some threshold reactions like (n,p) and (n,α) on cadmium were carried out using the activation technique in combination with radiochemical separations and high-resolution γ-ray spectroscopy. Special attention was paid to the formation of ¹⁰³Pd via the ¹⁰⁶Cd(n,α) ¹⁰³Pd reaction since it is an important therapeutic radionuclide. At a fast flux neutron density of 7.5×10¹³ cm²s^-1 and an irradiation time of 120 h, using 100% enriched ¹⁰⁶Cd target 340 MBq of no-carrier-added ¹⁰³Pd per batch could be produced. The method is thus suitable for medium-scale production of this radionuclide.
