migration of radionuclide in soil and plants in the western ghats environment

background: a study on the migration characteristics of 238u, 210po, 232th and 40k 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. iran. j. radiat. res., 2008 6 (1): 7-12
