Personal and Environmental Exposure Assessment Measurements at Fernald

The research is directed to developing state-of-the-art personal and environmental exposure assessment for inhaled radionuclides at Fernald during D&D. An additional objective is the radiochemical analyses of soil samples taken around the radium (K-65) silos before and after removal of the material. Lead-210, the long lived decay product of radon released during the removal, provides a sensitive tracer to determine the entire inventory of radon released
