| Abstract: | The paper presents the results of measurements on air and soil samples collected for their natural and artificial radioactivity content. The radionuclides studied under this programme are 7Be and 137Cs. Average activity concentrations in surface air of 7Be and 137Cs were found to be 1920 and 2.1 μBq m‐3, respectively. 137Cs activity concentration in surface soil is found to be 450m Bq kg‐1. Estimated effective doses to adult from inhaled 7Be and 137Cs were found to be 1 and 0.13 nSvy‐1, respectively. The average outdoors absorbed dose rate in air, 1 m above the ground level was found to be (48 ± 4.0 nGy h‐1), based on the analysis of thermoluminescence dosimeters data collected. |
