“…Activity levels of 210 Po and 210 Pb in mosses were compared with similar studies in the literature (Table 4). 210 Po activity levels in mosses were lower than levels found in Syria; however, 210 Po activity was higher than levels found around the CFPP at Pontain, Johor (Table 4) [27,28]. In addition, 210 Pb activity in mosses in the current study is consistent with that found in Thailand and Serbia, although 210 Pb activity was lower than in Syria (Table 4) (Table 4) [9].…”

“…However, it was indicated that the range of 210 Po/ 210 Pb ratio (0.3-0.7) in lichens was lower than unity in another study [29]. Also, Al-Masri et al (2005) determined higher activity concentrations of 210 Pb compared with 210 Po in mosses at some locations along the Syrian coastal mountain range [28]. The basic source of 210 Po and 210 Pb in the atmosphere is decay of 222 Rn, which is the most mobile decay product of the 238 U decay series.…”

This paper deals with determination of 210 Po and 210 Pb activity concentrations using epigeic moss (Hypnum cupressiforme), bushy soil (fruticose) lichen (Cladonia rangiformis) and surface soil samples in the area around Ç an coal-fired power plant, northwest Turkey. Mean activity concentrations of 210 Po and 210 Pb were found to be 303.9 and 425.8 Bq kg -1 for moss, 161.6 and 259.1 Bq kg -1 for lichen, and 79.9 and 91.5 Bq kg -1 for soil samples at dry weight, respectively. We propose that distance and altitude of sampling site may be of significant parameters of distribution of both radionuclides.

“…ours was the 2 cm interval from the upper-most down to a depth of 12 cm. High 137 Cs concentration in soil (4933 Bq kg −1 ) was also obtained at mountain regions along the coast of the eastern Mediterranean Sea in Syria by Al-Masri et al [14], who measured several radionuclides including 137 Cs and 210 Pb in two most common mosses (Lycopodium cernuum and Funaria hygrometrica) and also in soil. Karadeniz and Yaprak [15] investigated geographical and vertical distribution of 137 Cs in coniferous forest soils in Izmir, Turkey.…”

With respect to long-term dynamics of fission products in forests, slow migration continues to take place with a great variety of migration rates de-the major purposes of our study is to elucidate local environments in undisturbed forest soils using several radionuclides such as 14 C, 40 K, 137 Cs, 210 Pb and 222 Rn as tracers [5]. A set of data obtained in various local environments will be compiled to identify the underlying principles controlling distribution of environmental radionuclides.…”

Tracing depositional consequences of environmental radionuclides (137Cs and 210Pb) in Slovenian forest soils

et al. 2011

Depth distribution profiles of environmental radionuclides (137Cs and 210Pb) have been investigated in soil to elucidate the underlying environment of semi-natural temperate deciduous and/or coniferous forest soils in Slovenia (Žirovski vrh, Idrija, Kočevski Rog, Pohorie, Gorišnica and Rakitna). Surface enrichment of both nuclides was observed at all the sites investigated in this study, suggesting that the soils had undergone little natural or anthropogenic disturbance for at least the last several decades. Apparent annual burial rates of 137Cs (0.1–0.2 cm y−−1) were estimated to be about 1.3 times higher than those of 210Pb at individual sites of different lithology, which suggests strong affinity of 210Pb to soil organic matter. Variability of the vertical distribution profiles of these nuclides depends not only on “in situ” pedology but also on geographical and meteorological conditions, especially precipitation and wind direction.

Transfer of radionuclides to ants, mosses and lichens in semi-natural ecosystems

There is a scarcity of data on transfer of both natural and anthropogenic radionuclides to detritivorous invertebrates for use in the assessment of radiation exposure. Although mosses and lichens have been extensively used in biomonitoring programs, the data on transfer of radionuclides to these species are limited, particularly for natural radionuclides. To enhance the available data, activity concentrations of (137)Cs, (226)Ra and (228)Ra were measured in ants, mosses and lichens and corresponding undisturbed soil collected from semi-natural ecosystems in Serbia and Montenegro and biota/soil concentration ratios (CR) calculated. Since the majority of internal dose to biota is expected to come from (40)K, the activity concentrations of this radionuclide were also determined. The mean CR values for (137)Cs, (226)Ra and (228)Ra in ants analyzed in this study were found to be 0.02, 0.06 and 0.02, respectively. The mean CR values of radionuclides in mosses were found to be 2.84 for (137)Cs, 0.19 for (226)Ra and 0.16 for (228)Ra, while those in lichens were found to be 1.08 for (137)Cs, 0.15 for (226)Ra and 0.13 for (228)Ra. The CR values obtained in this study were compared with default CR values used in the ERICA Tool database and also with those reported in other studies.
