The investigation of radionuclide distributions in soil samples collected from Bursa, Turkey.
The distributions of (226)Ra, (232)Th, (40)K and (137)Cs activity concentrations were determined using a high-purity germanium detector in uncultivated surface soil samples collected from Bursa. The range of (226)Ra, (232)Th, (40)K and (137)Cs activity concentrations varied from 10±1 to 61±3 Bq kg(-1) (mean value 25±3 Bq kg(-1)), from 12±1 to 50±2 Bq kg(-1) (mean value 26±3 Bq kg(-1)), from 257±5 to 1010±11 Bq kg(-1) (mean value 435±44 Bq kg(-1)) and from 1.01±0.07 to 48.97±0.54 Bq kg(-1) (mean value 8.52±2.59 Bq kg(-1)), respectively. In addition, the mean outdoor absorbed dose rates in air, annual effective dose equivalent, radium equivalent activity and external hazard index were found to be 45 nGy h(-1), 56 μSv y(-1), 96 Bq kg(-1) and 0.26, respectively. The gross beta activity concentrations were determined using a Tennelec LB 1000-PW detector. The range of gross beta activity concentrations varied from 46±9 to 1199±113 Bq kg(-1) with a mean value of 541±19 Bq kg(-1).
