Executive Summary

This research seeks to develop a nuclear cloud rise and fallout model based on first-principles for use in modeling detonations in complex environments. If successful, this fundamental research will support homeland security missions through an improved understanding of nuclear detonations and the subsequent fallout processes in real-world conditions.
