“…It could be considered in terms of features of localities: this occurred in coniferous forests (mosses in pine and spruce forests more readily uptake radionuclides than oak forests), and it could be related with acidic conifer needles, its retaining the soil moisture and making different substrate. Džoljić et al (2017) reported very low TF Cs for spruce needles (range from not detected to 0.02), which could confirm washing out effect and deposition in substrate by precipitation. The most important way of 137 Cs deposition in moss tissue is possibility that 137 Cs remains on the surface, which influences soil resuspension and transport to mosses (Ioannidou & Papastefanou, 2006, Krmar et al, 2018; also, 137 Cs can be transported during growing period from older sections to newer sections of moss tissue (Krmar et al, 2018).…”

This paper deals with investigations of elemental concentrations and soil-to-moss transfer factors of radionuclides in area of municipalities Kosovska Mitrovica and Zubin Potok. Twelve samples of soil and moss Hypnum cupressiforme Hedw. were collected during May 2018. Transfer factors of radionuclides: 226Ra, 232Th, 40K and 137Cs were calculated with regard to elemental concentrations of radionuclides in soil and moss samples. Analysis was done in order to indicate the different ways of adopting radionuclides by mosses. According to calculated transfer factors and analysis, authors concluded that the soil is dominant source of natural radionuclides and their concentration in moss occurred due to resuspension of soil particles, while artificial 137Cs is present in soil and moss samples as a consequence of atmospheric dry and wet deposition.

“…In addition to the natural radionuclides, the artificial 137 Cs was detected in the soil, grass, spruce, cow milk and moss samples from Mt. Kopaonik (Mitrović et al, 2016;Džoljić et al, 2017). In the soil, the lowest activity concentration of 137 Cs was recorded in the area of Pančićev vrh, and the maximum in Jošanjička banja (Table 5).…”

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.

The aim of the study was to evaluate the potential risks of radiation near abandoned uranium mines, tailing dumps, or uranium deposits on Mountain Stara Planina, Serbia. For risk assessment several parameters were determined: radium equivalent activity, Raeq, external hazard index, Hex, gamma radiation absorbed dose rate, D, annual effective dose on background outdoor gamma exposure, AEDoutdoor, and excess lifetime cancer risk, ELCR. Obtained results showed that all the samples, except one, have the Raeq value up to two times higher than the reference limit. The Raeq of the sample from the Mezdreja mine tailings was increased by almost eight times. The value of Hex followed the same pattern as Raeq. All the investigated localities have increased D values, while all the samples have shown the moderately low AEDoutdoor, except Mezdreja mine tailings that have 5.5-2.8 times higher dose relative to the world's average. ELCR at the Mezdreja mine tailings is 4.58 times higher than the world's average of 1.45?10?3. In the context of human activity in the area of Stara Planina such as different kinds of tourism, livestock breeding, dairy products, and herbal manufacturing, etc. there is a need for detailed analysis in order to evaluate potential human exposure and health impacts.
