|Abstract:|| The United States filmed 210 atmospheric nuclear tests throughout the 1950s and 60s. These approximately 7,000 films represent irreplaceable and unique data that has been foundational to our understanding of post-detonation physics over the past 60 years. Using modern computer technology we now have the capability to scan these films into a high-resolution, digital format. Different methods of computerized image analysis of digital nuclear fireball films are validated in this report. Additionally, the results for the analysis of 35 early-time fireball films taken from multiple test shots performed during Operation Teapot are presented. These results produce new time and yield dependent models of tmin, t2max, and fireball radius. The new equations are also compared against models proposed in previous research and the possibility of more accurate predictions of fireball behavior is explored. This report provides the framework for developing future software to analyze filmed detonations of nuclear weapons.
