Abstract
The aim of this research is estimating the total radioactivity for the High Level Liquid Waste pool (HLLW) in the radiochemistry waste hall in Al-Tuwaitha site. The collected samples from this pool analyzed by using two techniques, the first is gamma spectroscopy system with High Purity Germanium Detector (HPGe) to measure the radioactivity concentration of gamma-ray emitters and to identify their isotopes. The results of measurements show that the average radioactivity concentration of Cesium (137Cs) equal to 2.085 MBq/L. The second technique is gross alpha beta counter by using (LUDLUM 3030) device with zinc sulfide scintillation detector ZnS (Ag) to measure the radioactivity concentrations of the other radionuclides which are not gamma-ray emitters for the same samples that can not be detected in the first method. Cesium-137 has separated from these samples by evaporation process because it also emmit beta particles associated with gamma photons, the remaining activity is (3.0054 MBq/L). According to work history of the radiochemistry laboratories this waste is nuclear fission products for Uranium-235 (235U) isotope, therefore, the remaining activity refers to Strontium-90 (90Sr) radionuclide due to its long half-life.
