Popis: The specific activities of natural radionuclides, 232Th, 226Ra, and 40K, in a Chinese iron beneficiation plant and surrounding soil were analyzed with the high purity germanium gamma (HPGe) spectrometer in this study. Average specific activities of 238U, 232Th, 226Ra and 40K lower than the Chinese averages. To assess radiation impact, various indicators, radium equivalent index (Raeq), absorbed dose rate (DR), annual effective dose (AED), excess lifetime cancer risk (ELCR), external hazard index (Hex), internal hazard index (Hin) and activity utilization index (AUI), were calculated. Mean values were below international limits, indicating no significant health hazards for the local population. Statistical analyses, including skewness and kurtosis calculations, along with techniques like frequency distribution, Pearson's correlation analysis, box plots and cluster analysis, were applied to comprehensively assess distribution patterns and interrelationships among radiological parameters. In summary, there are no potential health hazards associated with the soil in the study region for people.
