Research Progress on Reducing Radioactive Nuclides in the Environment
238U,232Th,226Ra and 40K in radionuclides are highly toxic and can be transmitted through the food chain,food web and other ways,posing long-term radiation hazards to human health.These substances still show high radio-activity even after grinding,high temperature,sintering and other methods.At present,it is urgent to find a practical method to solve the problem of radioactivity.In this review,the reduction of radionuclides in the envi-ronment is elaborated by physical,chemical and biological methods,and its principle and main advantages and disad-vantages are briefly introduced and reviewed,and the development trend of the future reduction of radioactivity is expected to provide valuable reference for the related work in the reduction of radioactivity.
