Exploring the Radioactive Nexus: Multidimensional Correlations and Dosimetric Assessment of Elemental Radionuclides

Abstract

Abstract This study examines the radioactivity levels in Tunisia influenced by geological diversity and socio-economic influences. The region's landscapes are characterized by abundant mining and industrial activities, particularly phosphate mining and chemical sectors. Statistical analysis reveals that average radioactivity in the air (0.104 µSv) is lower than in soil (0.158 µSv) due to air dilution. Positive correlations are observed between air and soil radioactivity levels. Spatial distribution mapping shows higher radioactivity concentrations in mining and industrial areas. Radiation risk assessment calculates Ambient Dose Index (ADI), Equivalent Effective Dose Index (EDEI), and Excess Lifetime Cancer Risk (ELCR) have been evaluated. ADI values exceed WHO standard for infants and children. EDEI ranges from 0.006 to 0.309, with 54.2% of samples surpassing the standard value of 0.1. ELCR for a 40-year lifespan varies from 0.013 to 0.619. Continuous monitoring and protective measures are vital to reduce health risks associated with ionizing radiation exposure. The study emphasizes the need for safeguarding public health in regions with significant mining and industrial activities and raises awareness of potential health hazards related to high concentrations of radioactive elements.
