Accumulation of radionuclide in aquatic plants and fish can reach to the human food chain. Studies of bioaccumulation characteristics of various aquatic species growing over the fresh water ecosystem is essential for long term planning of industrial waste disposal in ecosystem. Aquatic plants such as algae, Eichornia, Hydrilla etc. and plants growing over sediment like Polygonum barbatum and Cyndon dectylon were analyzed for radionuclide uptake. Different fish species are also analyzed for radionuclide content. Biological uptake of radionuclide fish species found to be very low and subsequent radiation dose due to U and 226 Ra through ingestion is 1.1Sv. Compared to dose received due to natural background radiation, the contribution from the fish intake is insignificant. Aquatic plants and fish species can concentrate natural radionuclide several orders of magnitude than water and sediment. The accumulation of radionuclide in aquatic plants and animals (fish) can reach to the human food chain. Apart from these, studies of bioaccumulation characteristics of various aquatic species growing over the fresh water ecosystem is essential for long term planning of industrial waste disposal in ecosystem. Since uranium mill tailings contain most of (80%) the radioactivity (238 U decay series like 230 Th, 226 Ra, 210 Pb, 210 Po etc) monitoring of biological uptake of natural radionuclide assumes importance in biotic and non biotic components of surrounding ecosystem.
