1. Micelle size effect on Fe-55 Liquid Scintillation Efficiency
Published: 12/1/2013
Authors: Denis E Bergeron, Lizbeth Laureano-Perez
Abstract: We used efficiency tracing techniques to study the micelle size effect on liquid scintillation counting of the low-energy Auger electron emitter, 55Fe. We determined micelle hydrodynamic diameters for specific LS cocktails via dynamic light scatteri ...

2. Investigation into the Standardization of Tc-99
Published: 7/30/2010
Authors: Lizbeth Laureano-Perez, Ronald Colle, Ryan P Fitzgerald, Brian Edward Zimmerman, Lonnie Talmadge Cumberland
Abstract: The standardization of 99Tc by several primary methods was investigated. This was performed to support a new 99Tc transfer standard that has been developed and will be disseminated by the National Institute of Standards and Technology (NIST) as Stan ...

3. A New Primary Standardization of Th-229
Published: 1/7/2010
Authors: Ryan P Fitzgerald, Lizbeth Laureano-Perez, Michelle M. Hammond, Leticia S Pibida, Svetlana Nour, Brian Edward Zimmerman
Abstract: The National Institute of Standards and Technology (NIST) has certified a high-purity Th-229 Standard Reference Material as SRM 4328C, based on live-timed 4-pi alpha,beta-gamma anticoincidence counting (LTAC) of the equilibrium solution. The LTAC sy ...
