Migration of radionuclide in soil and plants in the Western Ghats environment

U, 210 Po, 232 Th and 40 K within the soil to the wild plants in the Western Ghats were carried out. Materials and Methods: Concentrations of these radionuclides were measured in different depths of soil and from different species by employing gamma ray spectrometer and alpha counter. Results: The activity concentration of these radionuclides varied faintly within the soil but widely varied within the plant and between the species. Conclusion: The CR (Concentration ratio) showed wide variation in different species, while a few species of wild plants such as Evodia roxburghiana, Eleaocarpus oblangus and Glochidion neilgherense indicated preferential uptake of these radionuclides.
