Evaluating the Radiological Hazards of Contaminated Soil with Natural Radioactive Materials (NORM) Resulting from Produced Water during Oil & Gas Production
نویسندگان
چکیده
Uncontrolled disposal of oilfield produced water in the surrounding environment could lead to soil contamination by naturally occurring radioactive materials (NORM). Large volumes become highly contaminated with radium isotopes (226Ra and 228Ra). The concentration radionuclides 226Ra, 232Th 40K were determined using gamma ray spectrometry order assess radiological health hazards excess lifetime cancer risks associated use soil. mean activity concentrations found be 1939.56, 737.86 and198.21 Bq kg_1, respectively. results indices annual effective dose & risk estimated RESRAD obtained this study all higher than their worldwide values. This indicating danger discharging resulting from oil gas production into evaporation ponds without taking preventive measures that limit thus limiting workers' exposure natural materials.

Soil chemical changes resulting from irrigation with water co-produced with coalbed natural gas.
Land application of coalbed natural gas (CBNG) co-produced water is a popular management option within northwestern Powder River Basin (PRB) of Wyoming. This study evaluated the impacts of land application of CBNG waters on soil chemical properties at five sites. Soil samples were collected from different depths (0-5, 5-15, 15-30, 30-60, 60-90, and 90-120 cm) from sites that were irrigated with...
