Bioremediation of low-level radionuclide contaminated soils and water

Abstract

Abstract: Different anthroponic factors have led up to increasing background concentrations of radionuclides in human ecosystems.As long as these radionuclides enter into soil-water substrates,they can pose hazards to human health through different pathways.Since most conventional chemical or physical procedures are not practical for dealing with low-level radionuclides in the water-soil substrates,new remediation technologies are being developed to tackle the problem.Bioremediation has attracted much attention because of its many advantages such as low cost and less environmental disturbance.The present paper summarizes the sources of radionuclides and introduces the concept of low-level radionuclide bioremediation.The state of the art in the field of bioremediation of low-level radionuclide contaminated water-soil substrates has also been reviewed and summarized in this paper.On the basis of above mentioned discussions the future developing trends were put forward.

Key words: Low-level radionuclides, Bioremediation, Pollutant
