Title: Analysis of Spectral Variation in Background Gamma Radiation at U.S. Ports of Entry

This project exists to improve the ability to detect nuclear material crossing the borders. The purpose of my portion of this project was to analyze spectral variations of backgrounds measured by radiation portal monitor detectors at ports of entry using available data to determine whether or not the measured background variation includes changes in the spectral shape in addition to changes in the gross counts.
