- The distributions of ²²⁶Ra, ²³²Th, ⁴⁰K and ¹³⁷Cs activity concentrations were determined using a high-purity germanium detector in uncultivated surface soil samples collected from Zonguldak. The range of ²²⁶Ra, ²³²Th, ⁴⁰K and ¹³⁷Cs activity concentrations varied from 10.5 ± 2.0 to 98.0 ± 4.3 Bq kg¯¹ (mean value 28.8± 4 Bq kg¯¹), from 12.9 ± 3.4 to 53.2 ± 5.1 Bq kg¯¹ (mean value 29.6± 3 Bq kg¯¹), from 190 ± 22 to 808 ± 43 Bq kg¯¹ (mean value 395± 31 Bq kg¯¹) and from <0.5 to 47.1± 3.8 Bq kg¯¹ (mean value 12.5± 2 Bq kg¯¹), respectively. In addition, the mean outdoor absorbed dose rates in air (terrestrial, terrestrial+cosmic), annual effective dose equivalent, radium equivalent activity and external hazard index were found to be 48 nGy h¯¹ (terrestrial), 56 nGy h¯¹ (terrestrial+cosmic), 58 μSv y¯¹, 101 Bq kg¯¹ and 0.27, respectively. The evaluated excess lifetime cancer risks (ELCRs) varied from 0.13× 10¯³ to 0.36× 10¯³ with a mean value of 0.20× 10¯³.
