Distribution and uptake of 137Cs in relation to alkali metals in a perhumid montane forest ecosystem

Accumulation of 137Cs and 40K in aboveground organs of tropical woody fruit plants

“…Based on the study of contaminated plants, our results have shown a significant correlation between activity concentrations of 137 Cs and 40 K in different compartments of plants [1,2]. Similar findings have been suggested during the investigation on the distribution and uptake of 137 Cs and the alkali metals in plants [3][4][5]. Despite there are large differences in the degree of translocation of inorganic cations in the above-ground parts of different species, depending upon physiological habits of the plants [4], some works have suggested the possibility of using the behaviour of alkali metals to predict the 137 Cs behaviour in soil-plant systems [3,5].…”

Correlations between potassium, rubidium and cesium (133Cs and 137Cs) in sporocarps of Suillus variegatus in a Swedish boreal forest

“…For detailed measurement procedures, see Rodushkin et al (2008). Element concentrations are reported as mg kg À1 d.w. and the isotopic ratio of 137 Cs/ 133 Cs was calculated with Equations (1) and (2) (Chao et al, 2008):…”

Cesium (137Cs and 133Cs), Potassium and Rubidium in Macromycete Fungi and Sphagnum Plants

“…The detection limits were 200 mg kg −1 for K, 0.04 mg kg −1 for 133 Cs and 0.008 mg kg −1 for Rb. The isotopic (atom) ratio of 137 Cs/ 133 Cs was calculated with Equations 1 and 2 (Chao et al, 2008 Cs and 133 Cs) and neighboring alkali counterparts K and Rb in different segments of plant provide information on differences in their uptake, distribution and relationships. The averaged 137 Cs activity concentrations in Sphagnum segments are presented in Figure 5a.…”
