The area of oil and gas production may have more noteworthy radioactivity levels, due to the disposal petroleum pipes containing sludge and scale as a technologically enhanced natural occurring radioactive material (TENORM) which leads to potential radiological and health dangers. The specific radioactivity concentrations of ²²⁶Ra, ²³²Th, and ⁴⁰ K in 124 of soil and waste petroleum samples such as sludge (from waste pit) and scale contained in the disposal petroleum pipes in the area of oil and gas production of the Thi-Qar province, southeast of Iraq were measured using the gamma-ray spectrometer. The measured samples were collected from six different locations. The average values of the specific concentrations of ²²⁶Ra, ²³²Th, and ⁴⁰ K of all samples were less than the release level recommended by the IAEA. The highest radioactivity concentrations of ²²⁶Ra, ²³²Th, and ⁴⁰ K among the different investigated samples were 19.90 Bq/kg (sludge), 20.06 Bq/kg (soil) and 480.33 Bq/kg (soil), respectively. The obtained results have been compared with the previous works in different regions in Iraq and the world average values specified by the UNSCEAR reports. The radiological indices such as radium equivalent, external hazard index, radiation dose rate and effective dose were determined, and their values were lower than the recommended regulatory limits. Thus, this study confirmed that exposure to the natural radiation coming from the soil or any petroleum materials in the area of oil and gas production of the Thi-Qar province did not present any significant radiological hazard to the public and the workers.

由于处置含有污泥和水垢的石油管道作为技术上增强的天然放射性物质（TENORM），因此油气生产领域的放射性水平可能更值得注意，这会导致潜在的放射学和健康危害。 在Thi-油气生产区中，土壤和废弃石油样品（如污泥（来自废物坑））中的²²⁶ Ra，²³² Th和⁴⁰ K的比放射性浓度，包括污泥（来自废物坑）和处置石油管道中所含的水垢。使用伽马射线能谱仪测量了伊拉克东南部的加尔省。从六个不同的位置收集测量的样品。²²⁶ Ra的特定浓度的平均值 所有样品的²³² Th和⁴⁰ K均低于国际原子能机构建议的释放水平。最高放射性浓度为²²⁶ Ra，²³² Th和⁴⁰ 不同调查样本中的K分别为19.90 Bq / kg（污泥），20.06 Bq / kg（土）和480.33 Bq / kg（土）。将获得的结果与伊拉克不同地区的先前工作以及UNSCEAR报告指定的世界平均值进行了比较。确定了放射学指标，如镭当量，外部危害指数，辐射剂量率和有效剂量，其值低于建议的监管限值。因此，这项研究证实，在提卡尔省的石油和天然气生产地区，土壤或任何石油材料所产生的自然辐射暴露不会对公众和工人造成任何重大的放射危害。
