Abstract: Potassium-40 (K-40) is a naturally occurring radioactive isotope that contributes to environmental radiation exposure. As an essential element in biological systems, K-40 is present in soil, water, food, and human tissues, making exposure unavoidable. However, the radiological impact of K-40, particularly in Nigeria, has not been thoroughly studied. This review examines the sources, distribution, and health implications of K-40 exposure in Nigeria, taking into account dietary intake, environmental factors, and occupational exposure. It evaluates existing studies on radiological assessments in the country and highlights gaps in regulatory frameworks for radiation protection. The paper also discusses potential health risks, including internal radiation dose implications, and suggests strategies for improving monitoring and public awareness. Strengthening radiation safety regulations and conducting further research on K-40 exposure pathways are essential for effective risk management.
