Background: Investigation on the natural
radionuclides 238U, 232Th, 40K and natural fallout
radionuclide 210Po in the prominent plants species of
Western Ghats tropical forest near Kotagiri have
been carried out as a part of baseline background
radiation studies in the forest environment.
Materials and Methods: The prominent plants
species of the region Evodia roxburghiana and
Eleaocarpus oblangus were chosen and
concentrations of 238U, 232Th, 40K and 210Po were
measured by employing gamma ray spectrometer
and alpha counter. Results: The radioactivity
concentrations in plants and soils 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 results shows that the
concentration ratios (CR) seem to be depend on
radionuclides in soil. Conclusion: From careful
analysis of the results, these plants could be used as
an indicator to monitor these radonuclides. |
