Abstract
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 2.3·10 13 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.
