Integrated Human Health and Radiological Risk Assessment of Heavy Metals and Naturally Occurring Radionuclides in Soil and Water from Oil

Sanda Yusuf Sadau, Ishaya Iliyasu, Atipo Kolawole M, Ojo Emmanuel O, Obonyilo Edache Gabriel, Tina Abinbola Adeniji & Oyadiran Wuyi Jonathan · Asian Journal of Research and Reviews in Physics · 2026

Oil and gas exploration can both introduce and redistribute potentially toxic metals and naturally occurring radioactive material across the soils and water bodies of surrounding communities, opening exposure pathways that reach well beyond the immediate production site. This stu...
