The levels of 238U, 232Th, and 40K with gross alpha and beta values in soils collected from the Kahramanmaraş city center were measured in this study, and the annual effective dose equivalent (AEDE), excessive lifetime cancer risk (ELCR), and terrestrial absorbed gamma dose rates were calculated for gamma radiation from 238U, 232Th, and 40K radionuclides. The samples' gross alpha and beta radioactivity concentrations, respectively, range from 0.06 ± 0.01 Bq/kg to 0.45 ± 0.04 Bq/kg and 0.14 ± 0.02 Bq/kg to 0.95 ± 0.09 Bq/kg. The Kahramanmaraş province's soil samples have mean gross alpha and beta radiation values of 0.25 ± 0.03 Bq/kg and 0.52 ± 0.05 Bq/kg, respectively. 238U, 232Th, and 40K activity concentrations in soil samples range from 2.32 ± 0.2 Bq/kg to 40.10 ± 1.4 Bq/kg, 0.60 ± 0.03 Bq/kg to 10.47 ± 1.01 Bq/kg, and 11.60 ± 1.01 Bq/kg to 160.84 ± 4.6 Bq/kg, respectively. 238U, 232Th, and 40K each had average activity concentrations of 11.50 ± 1.1, 4.50 ± 0.4, and 62.20 ± 1.6 Bq/kg in soil, respectively. The annual effective dose equivalent (AEDE), excessive lifetime cancer risk (ELCR), and terrestrial absorbed gamma dose rate range from 0.01 ± 0.01 μSv y-1 to 0.03 ± 0.02 μSv y-1, and 0.01 ± 0.01 × 10-3 to 0.12 ± 0.03 × 10-3, 1.72 ± 0.01 nGy h-1 to 25.05 ± 0.21 nGy h-1, respectively. Additionally, the average annual effective dose equivalent (AEDE), average excessive lifetime cancer risk (ELCR), and average terrestrial absorbed gamma dose rates are 0.01 ± 0.01 μSv y-1, and 0.05 ± 0.02 × 10-3, 9.81 ± 0.09 nGy h-1, respectively. The acquired data were compared to both domestic and international standards.
