Study on Decontamination from Contaminated Soil by Technologically Enhanced Naturally Occurring Radioactive Materials in Oil and Gas Production Fields in the western desert

Abstract

The presence of large quantities of TENORM contaminated soil produced during the extraction and processing of crude oil at oil extraction sites and low cost methods to decontaminate this radioactively contaminated soil. In this respect, the leaching behavior of the radionuclides from the TENORM contaminated soil samples by different concentration of natural leaching solutions were studied. A series of batch experiments have been conducted to determine leaching behavior of the radionuclides onto the solutions and the different factors affecting the leaching process have been studied. The aim of the present work is to elucidate the risk of TENORM to the environment and to initiate methods to deal with the resulting contaminated soil by the following methods: 1-Removel of 226Ra from contaminated soil samples by electrodeposition technique using different electrods materials. 2-Remediation of contaminated soil by washing technique using different leaching solutions.
