Determination of rare earth elements in phosphorites by neutron activation analysis

  • S. M. Al-Jobori
  • Y. A. H. Kettaneh


Fourty three phosphorite rocks from Western Iraq were analyzed for eleven REE as well as uranium by NAA using IRT Reactor with a neutron flux of 2.3·1013 n·cm−2·s−1. The gamma activity from each sample was counted with a Ge(Li) and well-type HPGe, each detector connected to an on-line computer. Uranium fission products and different reaction interferences were assessed and allowed for. The results were also checked against international reference materials.
