The fate of radioactivity in marine environments resulting from oil spills is a complex issue, and its transportation and management are very crucial. This chapter highlights the presence of Naturally Occurring Radioactive Materials (NORM) in crude oil and the potential environmental and health risks associated with spills. It emphasizes the importance of understanding the transport and management of these radioactive contaminants. The analysis examines the sources and behavior of radionuclides in oil spills, it identifies common radioactive elements present in oil, how they are released during spills, and factors influencing their transport and fate. Additionally, it discusses how radioactive contaminants transport through various pathways, including the spread and dispersal of oil slicks, the distribution of radionuclides among oil, water, and sediments, and the potential for bioaccumulation and biomagnification in marine ecosystems. Effective management strategies for radioactive oil spills are outlined, highlighting the need for optimal practices tailored to this specific challenge. The exploration of disaster management strategies for such incidents is also included. Overall, this comprehensive overview provides valuable insights for scientists, policymakers, and response teams dealing with the complex challenge of radioactive contamination in marine oil spills.
