【 摘 要 】

The overall goal of this project was to develop quantitative FTA to provide images of the microscale spatial distributions of high fissile actinides sorbed to environmental particles such as sediments and colloids. We developed methods to provide absolute actinide surface concentrations on the particles, regardless of particle size. We are also working to provide particle size information by our approach. We also coupled our newly devised FTA methods with the quantitative determination of stable element distributions in the same particles using synchrotron x-ray microprobe analysis.
