Abstract

The activity concentrations of twenty soil samples collected from contaminated locations of Fuel Fabrication Facility (FFF) at Al- Tuwaitha nuclear site, Iraq, were determined by using spectroscopy with a high purity germanium detector. The range of activity concentrations of ²³⁸U (^234mPa), ²³⁵U, ²³²Th (²²⁸Ac), and ⁴⁰K in the soil from the studied areas varies from (177.74±60) to (375777.5±6895) Bqkg^-1, (7.4±0.5) to (20954±407.5) Bqkg^-1, (7.06±0.22) to (20.45±0.33) Bqkg¹ and from (47.5±5.3) to (402.2±15.5) Bq kg^-1 respectively. The isotopic mass and activity ratio of ²³⁵U/²³⁸U were calculated to identify kind of uranium, depleted or natural. To assess the radio logical risk for this site, RESRAD program was used to calculate total dose from all pathways (external, inhalation and soil ingestion) of exposure, the value of total dose was 2mSv/yr. Laboratory results indicated that the FFF was contaminated with ^234mPa and ²³⁵U nuclides in excess of the IAEA limits for exemption from regulatory control, and indicating that the decommissioning operations for the FFF must be subjected to regulatory control and safety surveillance to ensure adequate protection of the operators, public and the environment.
