Abstract

The Hanford Site in southeastern Washington State produced plutonium for the United States nuclear weapons program from 1944 to 1988. Large quantities of highly radioactive waste were generated as a result, and cleanup continues today. Since the early days, gamma measurements in boreholes have been recognized as a means to detect and monitor radioactive contaminants in the subsurface. Total gamma and spectral gamma data have been collected with a variety of detectors over the years. Early data consisted of written records of count rates, and later, strip charts. Log data are available in electronic format from as early as the mid-1970’s. High-resolution spectral gamma detectors have been used since the early 1990’s to provide identification and quantification of man-made radionuclides. There are several thousand wells and boreholes across the Hanford Site, and many of these have been logged multiple times over decades. This paper provides a general overview of gamma logging activities at Hanford and shows how integration and standardization of data from multiple detector systems can be used to establish a coherent history of contaminant migration over time.
