Available in PDF, EPUB and Kindle. Book excerpt: The purpose of Project 39.3 was to measure the thermal flux per unit area at a series of specified distances from a nuclear detonation. The instrumentation chosen was an Eppley thermopile indicating on a strip-chart paper recorder. Two stations failed to yield results because of power failures and blast damage. Results were obtained at 5500, 6800, 10,500 ft. These results follow the inverse-square-law fall-off, within the limits of reasonable experimental error.
