Natural and anthropogenic radioactivity concentrations of the 238U, 232Th, 40K and 137Cs in tea, plant and soil samples collected from the Black Sea region in Turkey were measured using a high-resolution HPGe gamma-ray detector at the Environmental Radioactivity Measurement and Research Laboratory, Istanbul University. The radioisotope activity concentrations in tea and plant samples varied between the minimum detectable activity (MDA) up to 98.43 ± 12.64 Bq kg−1 for the 238U, from below the MDA to 5.23 ± 2.33 Bq kg−1 for the 232Th, from 282.19 ± 6.76 to 784.55 ± 15.67 Bq kg−1 for the 40K and from 0.5 ± 0.11 to 43.23 ± 0.86 Bq kg−1 for the anthropogenic 137Cs. The activity concentrations of 238U, 232Th, 40K and 137Cs radionuclides in soils ranged from 24.75 ± 0.96 to 125.41 ± 13.35 Bq kg−1; from 16.55 ± 0.66 to 39.64 ± 5.49 Bq kg−1; from 340.91 ± 8.86 to 663.92 ± 12.62 Bq kg−1; and from 2.10 ± 0.79 to 143.97 ± 1.47 Bq kg−1, respectively. The annual effective doses (AEDs) for all samples and transfer factors of those radionuclides from soil to tea and soil to plant were also calculated. The results were compared with studies from other places in the world. This work provides a baseline study for the determination of background radiation in the Black Sea region.
