【 摘 要 】

The Oak Ridge National Laboratory, Grand Junction, Colorado, office was the Inclusion Survey Contractor and the Independent Verification Contractor (IVC) for the Uranium Mill Tailings Remedial Action (UMTRA) Project from 1983 to 1998. This report summarizes the activities performed during this time and discusses data collected and stored in four databases. The primary project management database contains 13,937 records that hold key information and logistics about each vicinity property. The second database contains technical information (sup 226)Ra in soil and concrete samples. A third database contains radon daughter concentrations. Finally, properties and pertinent information regarding the NC effort are stored in a fourth database. These databases are available on CD and are stored in the archives at the Department of Energy's Grand Junction Office. The analytical database is particularly valuable because it contains nearly 20,000 (sup 226)Ra results. Descriptive statistics of these data provide a variety of insights into the nature of mill- tailings contamination and also background levels of (sup 226)Ra at the UMTRA Project sites.
