Özet

The aim of this study is to create a radiological map of Klrşehir province in Turkey by analyzing the radioactivity levels of soil samples and environmental radiation measurements. 226Ra, 232Th, 40K and 137Cs radionuclides were analysed in soil samples collected from 47 locations using gamma spectrometry with an HPGe detector. According to the results obtained, gamma radioactivity concentration ranges and mean values for 226Ra, 232Th, 40K and 137Cs were determined as 133 ± 15-1515 ± 128 Bq/kg (599.40 Bq/kg), 0.3 ± 0.09-21.1 ± 1.7 Bq/kg (4.61 Bq/kg), 8.7 ± 0.9-128.5 ± 8.5 Bq/kg (29.66 Bq/kg) and 11.6 ± 8.6-273.8 ± 19.9 Bq/kg (48.80 Bq/kg) respectively. Average radioactivity levels for 40K and 232Th are above the world average. The mean radium equivalent activity (Raeq), gamma dose rate (D), annual effective dose equivalent (AEDE), external hazard index (H ex ), and the excess lifetime cancer risk (ELCR) were calculated as 145.45 Bq/kg, 122.13 nGy/h, 0.15 mSv/h, 0.39 and 0.29 × 10-3 respectively.
