Dissolved Oralloy standards and the origin of HEU

摘要

This report describes an analytical procedure for use in determining the heavy element content of a sample of HEU. Results of the analysis of a specific sample are discussed and some forensic signatures are identified. Two calibrated liquid samples were created, containing known amounts of HEU and contaminants. These samples were counted for gamma rays in the same way that an HEU sample would be treated, and results of the gamma counting are compared with the analytical results.
