A total of fifty-five soil samples were collected from four locations, namely, residential, industrial, dumpsite, and sewage in Agbara industrial estate, Ogun state, Nigeria. The samples were analyzed using a high purity germanium detector (HPGe) to measure the activity concentration of radionuclides. Background radiation measurements were also taken at each point where soil samples were collected using Geiger Muller (GM) counter. The mean activity concentrations measured in the soil samples were 171.33 for ⁴⁰K, 9.11 for ²³²Th, and 5.05 for ²²⁶Ra in Bq/kg. The mean absorbed dose rate in the air due to radionuclides (⁴⁰K, ²³²Th, and ²²⁶Ra) in the soil is calculated to be 14.77 nGy/h, and the mean annual effective dose equivalent (AEDE) is 0.02 mSv/year. The mean equivalent dose rate (EDR) from GM counter for background radiation is 0.22 μSv/h, and the mean annual effective dose rate (AEDR) is 0.39 mSv/year. These values are below the world average values, except EDR and AEDR with mean values higher than the world standard. The comparison of radiation dose rates revealed that radionuclides contributed 6.7% to background radiation. The equivalent dose (ED_organs) for various organs of the body was calculated, and results showed that values do not pose any immediate health hazard. The excess lifetime cancer risk (ELCR) due to exposure to background radiation indicated that the dwellers and industrial workers in the study area may develop cancer over a lifetime due to accumulated dose.

在尼日利亚奥贡州阿格巴拉工业区的四个地点（住宅，工业，垃圾场和污水）总共收集了55个土壤样本。使用高纯度锗检测器（HPGe）对样品进行分析，以测量放射性核素的活性浓度。还使用Geiger Muller（GM）计数器在收集土壤样品的每个点进行背景辐射测量。的土壤样品中测得的平均活性浓度分别为171.33为⁴⁰ K，9.11 ²³² Th和5.05 ²²⁶在贝/ kg的镭。放射性核素（⁴⁰ K，²³² Th和^226）在空气中的平均吸收剂量率计算得出土壤中的Ra）为14.77 nGy / h，年平均等效有效剂量（AEDE）为0.02 mSv /年。GM计数器对背景辐射的平均等效剂量率（EDR）为0.22μSv/ h，年平均有效剂量率（AEDR）为0.39 mSv /年。这些值低于世界平均值，但EDR和AEDR的平均值高于世界标准。辐射剂量率的比较表明，放射性核素对本底辐射的贡献为6.7％。等效剂量（ED_器官），计算出人体各个器官，结果表明该值不会对健康造成直接危害。由于暴露于背景辐射而导致的终生癌症风险过高（ELCR）表明，研究区域的居民和产业工人可能由于累积剂量而终生罹患癌症。
