Abstract
Mining and processing of uranium ore was started in several parts of eastern Singhbhum, viz. Jaduguda, Bhatin and Narwapahar (Jharkhand) in 1968. Radioactivity in the mine tailings has to be consolidated so that it does not emanate in the atmosphere or enter the food chain. Hence, the area has been covered with 30 cm thick soil cover followed by development of plant species that do not have any socioeconomic relevance in the area. Seven native plant species of forestry origin, viz. Colebrookea oppositifolia, Dodonaea viscosa, Furcraea foetida, Imperata cylindrica, Jatropha gossypifolia, Pogostemon benghalense and Saccharum spontaneum have been selected for experimental trials. Distribution and concentration of radionuclides have been evaluated in a tailing pond at different depths in soil and tailings. Radionuclide uptake in each of the selected plant species has been evaluated and discussed in this article. The highest concentration of radionuclides has been found in tailings > soil cover on tailings > roots of selected plant species > shoots of all the selected species. These results show that among the seven species tried, J. gossypifolia and F. foetida have the lowest uptake (below detectable limits), while S. spontaneum and P. benghalense have comparatively higher uptake. However, radionuclide concentration
