“…Mosses, lichens and mushrooms are typical representatives of bioindicator plants for radioactive contamination; by measuring the radionuclide activity levels a reliable insight into the contamination degree of ecological systems by radioactive isotopes is obtained [1], [6]. The accumulating capacity of moss is higher than that of other plants.…”

“…The accumulating capacity of moss is higher than that of other plants. They capture airborne particulates by both passive and active processes trough an extra cellular ion-exchange process [6]. Mosses adsorb radiocesium true the entire surface and become its reservoir [1].…”

“…Mosses, lichens and mushrooms are god representatives of bioindicator plants for both natural, and artificial radionuclide present in the environment. Mosses have some advantages because the accumulating capacity is higher than that of other plants and because they have a wide ecological and geological distribution, and are present during the whole year [6].…”

Abstract. The aim of this paper was to investigate the activity concentration of natural radionuclides 40 137 Cs in the environment of Stara Planina Mountain was measured in soil (22 Bq/kg) from the area of Smilovci and moss (26 Bq/kg) from the area of Kamenica. Radiocesium was also detected in houseleek (5.7 Bq/kg), while in animal feed and dairy products the activity concentration was below the detection limit.

This review paper discusses the content of natural ( 40 K, 238 U, 226 Ra, and 232 Th) and artificial ( 137 Cs) radionuclides in the soil of the mountains of Maljen, Tara and Kopaonik in the Republic of Serbia over 2002-2015. In addition, the paper gives radiation hazard parameters, i.e., radium equivalent activity, absorbed dose rate, annual effective dose equivalent, external hazard index, annual gonadal dose equivalent, and excess lifetime cancer risk outdoors that we calculated from the obtained content of the natural radionuclides in the soil samples. We compared the parameters to previously published results for different parts of the country and looked into the radioecological status of the investigated areas.

“…After the Chernobyl accident, the spatial and vertical migration of the 137 Cs in soil has become the main goal of a number of studies in Serbia (Bikit et al 2005;Dugalic et al 2010;Grdović et al 2010;Dragović et al 2012a;Petrović et al 2013). The aim of this study was to investigate vertical and spatial distribution of 137 Cs in soils in the southeastern Serbia, particularly the Pčinja and South Morava River Basins which is known as an area with very strong soil erosion.…”

Purpose The area of southeastern Serbia, the Pčinja and South Morava River Basins, is under the influence of very strong erosion, and the aim of this study was to investigate the vertical and spatial distribution of the 137 Cs in the eroded soils of this area. Materials and methods Vertical soil profiles were collected with 5-cm increments from the uppermost layer down to 20, 25, 30, 40, and 50 cm of depth, depending on the thickness of the soil layers, i.e., down to the underlying parent rocks. Measurements of 137 Cs activity concentration were performed by using the HPGe gamma-ray spectrometer ORTEC-AMETEK (34 % relative efficiency and high resolution 1.65 keV at 1.33 MeV for 60 Co), from its gamma-ray line at 661.2 keV. Results and discussion The mean 137 Cs activity concentration across all 18 soil profiles (for all soil layers) was found to be 20 Bq kg −1 . In the greatest number of soil profiles, the 137 Cs activity concentration was generally highest in the first soil layer (0-5 cm) and decreased with soil depth, while in a few soil profiles, the peak of either the 137 Cs activity concentration occurred in the second soil layer (5-10 cm) or the 137 Cs activity concentration was almost equal throughout the entire soil profile. The mean 137 Cs activity concentration in the first soil layer (0-5 cm) was found to be 61 Bq kg −1 , and the high coefficient of variation of 92 % pointed out high spatial variability and large range of the 137 Cs activity concentrations in the study area. Conclusions The obtained results indicate that in the greatest number of soil profiles, 137 Cs is present in the upper layers, with concentration decreasing with depth, as is typical in uncultivated soil. Its spatial distribution was very uneven among the surface soil layers of the investigated sites. One of the main reasons for such pattern of 137 Cs in the study area may be soil erosion. Additional investigations which would support this hypothesis are required.
