Abstract：Soil pollution caused by radionuclides has been increasingly concerned by government and public.Treatment and remediation of ecological environmental pollution in mining areas caused by uranium mine production has become a research hotspot in environmental protection industry.Remediation of radionuclide contaminated soil in uranium ore area includes physical remediation,chemical remediation and bioremediation.Soil excavation,mulching and cleaning are the first choice to deal with emergencies,which can play a role in expanding practical use of contaminated sites.For complex contaminated site,it is necessary to develop different remediation technology schemes with cost benefit and environment friendly according to actual situation,which will become mainstream choice of remediation technology of radioactive contaminated soil in uranium mining area.Basic theory,function mechanism and development current situation of physical repair technology,chemical remediation and bioremediation technology are systemly summarized.Study according to different field repair needs to formulate specific fix path is discussed.District standards development direction of uranium ore is prospected.Direction of setting standards for remediation of radionuclide contaminated soil in uranium mining area is prospected.It can provide theoretical support and guiding basis for bioremediation of uranium ore district radioactive nuclide uranium contaminated soil.
