【 摘 要 】

The DOE is currently conducting cleanup activities at its nuclear weapons development sites, many of which have accumulated plutonium (Pu) in soils for 50 years. To properly control Pu migration in soils within Federal sites and onto public lands, better evaluate the public risk, and design effective remediation strategies, a fundamental understanding of Pu speciation and environmental transport is needed. This type of information is increasingly important as the remediation and decommissioning plans for actinide-contaminated sites includes in situ stabilization or clean-up to a particular level of residual contamination. Long-term stewardship of the sites and return of these sites to public use will require more accurate predictions of contamination stability and mobility than is possible using current information.
