“…Much con cern has been ad dressed over the prob lem of soil con tam i na tion with heavy met als and or ganic pol lut ants due to rapid in dus tri aliza tion and ur ban iza tion [3,[7][8][9][10].

This study aims to obtain data on terrestrial radioactivity coming from naturally occurring (40K, 226Ra, 232Th, and 238U) and artificial (137Cs) radionuclides in surface soil (0-10 cm) of selected eighteen public-access urban areas in Krusevac city, Serbia, and to assess the corresponding health effects for citizens using those areas for recreational purposes. The specific activities of investigated radionuclides were analyzed using HPGe gamma-ray spectrometry. The mean specific activity of 40K, 226Ra, 232Th, 238U, and 137Cs was found to be 353, 39.8, 38.9, 41.0, and 5.9, respectively, in compliance with their values in other parts of Serbia and neighboring countries reported in similar researches. To evaluate the human health risk associated with radionuclides, conservative exposure assumptions and models recommended by the United States Environmental Protection Agency were employed taking into account three exposure routes: ingestion, inhalation of soil, and external irradiation. The absorbed gamma dose rate in the air due to natural radionuclides in soil was calculated. The calculated indices suggested that the radiation risk arising from natural and artificial radionuclides was not significant. The total excess lifetime cancer based on the 95 % upper confidence limit of the specific activities mean was calculated to be 5.89?10?6, lower than the tolerable risk for regulatory purposes (10?4). Among investigated radiation exposure pathways, external exposure was the most contributing one for the health risk. The results obtained for the city's parks and playgrounds suggested their safe use for recreational purposes from the radioecological point of view.

“…Since 222 Rn is the direct product of 226 Ra decay, in this study the correlation between measured indoor radon concentrations and the activity concentrations of 226 Ra in the soils in the yards of kindergartens and schools (presented in Table 1), determined earlier (Manić et al, 2019), were explored. The radon measurement results versus corresponding activity concentrations of radium are presented in the form of a scatter plot in Figure 2.…”

In this study, the activity concentration of radon, 222 Rn, in kindergartens and schools in the town of Niš, Serbia, was explored. The method of active charcoal was applied. The measurements were carried out by gammaspectrometry with HPGe detector. The results belong to the range of 15 Bq/m 3-256 Bq/m 3 , with an average value of 59.7 Bq/m 3 and a standard deviation of 25.3 Bq/m 3. It was shown that data are distributed according to the log-normal distribution, and that is no correlation between indoor 222 Rn concentrations and the activity concentrations of radium, 226 Ra, in the soil.
