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.EnglishAnnual Effective DoseNatural RadionuclidesPrincipal Component AnalysisSoil PhysicochemicalHumic AcidLeadPotassiumUraniumClayActivity ConcentrationAnnual Effective DoseNatural RadionuclidesPhysico - Chemical ParametersPhysico-chemicalsPositive CorrelationsPrincipal-component AnalysisRadioactive ConcentrationSoil Physico-chemical PropertiesSoil PhysicochemicalRadiation HazardsHumic AcidLanthanideLeadPotassiumThoriumUraniumArticleCancer RiskMachine LearningMaximum Permissible DoseNonhumanPhPhysical ChemistryPrincipal Component AnalysisRadiation HazardRadioactivitySoil PropertyArticle
