Determination of radon gas concentration 222Rn and other radioisotopes such as radium 226Ra in in Selected Oil Waste Models from Oil fields in Basra Governorate - Southern Iraq


In this study, 30 samples from the sludge produced as waste from the oil and gas industry were collected from the oil fields in Basra Governorate - southern Iraq to determine the concentrations of radon gas 222Rn and other radioactive isotopes such as radium 226Ra. Rapid electronic technology has been adopted by the Rational Application Developer RAD7 active method and Kama spectrum analysis technique using HPGe High Purity Germanium Detectors to determine the effective concentrations of radioactive elements. The results of this study showed that the largest concentration of radon gas in the (Sludge) is 58315 ± 3981Bq / m3 in sample No. L6) from the Zubair gas isolation station in the Zubair oil field and the lowest concentration of 1896 ± 129Bq / m3 in the Sludge sample from the eighth gas isolation station / West Quran field, as the study showed that there are high concentrations of radium 226 Ra of Bq / k 115731 in a model chosen from a high exposure site compared to its concentration of Bq / k 370 in the natural soil model according to OECD (Organization for economic and development). The effective annual dose was estimated for the highest radon concentration value that workers might be exposed to upon contact and found to be µSvh-1 166.43 ± 10.92 which is higher than the permitted dose level of 50 µSv h-1 recommended by the EPA in the United States.
