Radiological Impact of Geo-Pilot Plant after Decontamination

Abstract

      The Geo-Pilot plant had been designed and constructed in 1989 in the center of Baghdad at high population residence sector to protect the hydrated yellow cake from uranium Ore. The final radiological survey is performed on the Geo-Pilot Plant to demonstrate compliance with the appropriate release criteria. The field measurements were performed on a systematic grid of 404 cells. The samples of soil were collected and analyzed in the radioanalytical laboratory. The results of laboratory analysis satisfy the exclusion criteria established by the International Atomic Energy Agency(IAEA). The dose received by the decommissioning workers range from 0.25 – 0.42 µSv /y, which satisfy the occupational dose limit regulated by the IAEA of 20 mSv/y and 1mSv/y for public.

 The environmental impact of the use of the site for industrial scenario has been investigated using RESRAD computer code. The results indicate that the Geo-Pilot Plant meets the release criteria after dismantling, since none of the individual measurements or health risk assessment results exceed any of the established guidelines.
