Microstructures and speciation of radionuclides in natural environment studied by advanced spectroscopy and theoretical calculation

Abstract

The environmental behavior of radionuclides is mainly dependent on their speciation and microstructures at solid particles. The speciation and microstructures of radionuclides at molecular level can be achieved from advanced spectroscopy techniques and theoretical calculations. In this perspective, we give a brief introduction of the advanced X-ray absorption fine structure (XAFS) technique and theoretical calculation in the analysis of the speciation and microstructures of radionuclides in the natural environment, which is crucial to evaluate the physicochemical behavior of radionuclides in the environment.
