The results of the measurements of radionuclide transfer from soil to vegetation (Poaceae spp.) that conducted during 2010–2014, in free-ranged grazing regions in Greece, are presented in this work. The specific activities of ¹³⁷Cs, ²²⁶Ra, ²²⁸Ra and ²²⁸Th radionuclides were measured and the activity concentrations were calculated in samples of soil and grass obtained from several studied regions in Greece. The respective soil-to-plant radionuclide transfer parameters (as Concentration Ratio) were calculated and the results were analyzed in terms of spatial deviation caused by the different climate type among the studied regions, provided that the same plant and soil types are studied. The Concentration Ratios ranged from 0.02 to 2.5 for ¹³⁷Cs, 0.01 to 0.7 for ²²⁶Ra, from 0.07 to 1.1 for ²²⁸Ra, and, from 0.08 to 0.17 for ²²⁸Th. Although, the concentration ratios of the primordial radionuclides show some consistency among the different regions, significant differences are observed for ¹³⁷Cs, which may be particularly attributed to the different climatic types (according to the Koppen-Geiger climate classification) that govern these regions.

这项工作介绍了 2010-2014 年期间在希腊自由放牧地区进行的放射性核素从土壤转移到植被（禾本科）的测量结果。的具体活动¹³⁷ CS，²²⁶镭，²²⁸ Ra和²²⁸测量了从希腊几个研究区域获得的土壤和草样品中的 Th 放射性核素并计算了活度浓度。在研究相同植物和土壤类型的情况下，计算了各自的土壤-植物放射性核素转移参数（作为浓度比），并根据研究区域之间不同气候类型引起的空间偏差对结果进行了分析。的集中度从0.02到不等2.5 ^137个CS，0.01〜0.7为²²⁶镭，从0.07〜1.1 ²²⁸ RA和，为0.08〜0.17 ²²⁸th。尽管原始放射性核素的浓度比率在不同区域之间显示出一定的一致性，但观察到¹³⁷ Cs 的显着差异，这可能特别归因于控制这些区域的不同气候类型（根据 Koppen-Geiger 气候分类）。
