To determine the radioactivity levels in soil and evaluate the associated radiological impact, 58 topsoil samples from the town of Bitola and its environs were collected. Gamma spectrometry measurements indicated significant variability in activity concentrations, with median values for 40K, 226Ra, and 232Th exceeding global medians. Calculations for the absorbed dose rate and annual effective dose rate were performed to assess radiological health hazards for the residents. The obtained results were statistically processed, and maps of spatial distribution were prepared, clearly indicating the combined influence of geology and human activities on the outcomes.
