Abstract: This report documents the work performed to determine the newly assigned concentration for the spectral gamma-ray borehole calibration models. Thirty-two models, maintained by the U.S. Department of Energy, are included in this study, and are grouped into eight sets of four models each. The eight sets are located at sites across the United States, and are used to calibrate logging instruments. The assignments are based on in-situ logging data to ensure self-consistency in the assigned concentrations, and on laboratory assays of concrete samples from each model to provide traceability to the New Brunswick Laboratory (NBL) standards.
