Abstract

Soil and 2 wild plant species (Evodia roxburghiana and Eleaocarpus oblangus)have been collected from the western Ghats region and analysed for 210Po and238U. The radioactivity concentrations in plants and soil reflect the impact of the existence of igneous nature of rock in the area of study. Concentration ratios (CR) of these radionuclides, between plants and underlying soil, have been studied and the results shows that the concentration ratios (CR) seem to be depend on radionuclides in soil.

 

Key words: Primordial radionuclides, western Ghats, monazite, igneous rock, CR-concentration ratio.
