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. Compared to dose received due to natural background radiation, the contribution from the fish intake is insignificant.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
