Relationship between physicochemical parameters with radioactive concentration in soil and annual effective dose

This study aims to clarify the relationship between soil physicochemical properties and the concentration of natural radionuclides. Our results show that principal component analysis indicated a positive correlation between activity concentration and sand content, and a negative correlation between activity concentration and clay content, while other factors showed little information about clear correlations with concentration. The calculated total average dose and total cancer risk exceeds permissible limits for the public, indicating a significant potential health impact on human health. The results show that the area around the mine exhibits a potential radiation hazard. © 2025 Elsevier B.V., All rights reserved.
