Recreational zones play an important role in human life in urban environment. The activities of natural radionuclides and 137Cs were determined by low background γ-ray spectrometry in soil samples collected at two depths (0–5 and 5–20 cm) in 15 recreational zones of Moscow. The average activity concentrations of analyzed radionuclides were 519, 35.1, 29, 1.9, and 8.0 Bq/kg for 40 K, 232Th, 238U, 235U, and 137Cs, respectively. The distribution of natural radionuclides and 137Cs in soil profiles showed almost uniform distribution of natural radionuclides and decrease of 137Cs with the increase of the depth. A number of radiological indices, namely radium equivalent activity, external and internal risk assessment, gamma-index, annual effective dose, and excess lifetime cancer risk, were calculated to assess the level of radiological hazard for population. The values of calculated parameters are within the recommended safety limits, showing that soil in studied recreational zones does not pose a serious threat to human health. |
