Abstract

Multielements, including some rare earth elements, have been determined by k 0-NAA in three types of ore reference materials from Australia Nuclear Science and Technology Organization. The samples were irradiated in China Mianyang Research Reactor. High purity iron wire and Zr foil were used to monitor the neutron spectrum parameters (f, φ th) at irradiation positions. Uranium fission interferences for Nd, Ce, La were determined and corrected for by Ik0 method. The effective interaction depth was employed to normalize efficiencies at different counting positions. The results are in good agreement with the values reported other laboratories.

Keywords
