The attenuation of blast by the damage done to mostly wood-frame buildings in Hiroshima and Nagasaki was measured by Penney et al (1970) and provides a benchmark for nuclear blast effects in open terrain. This article examines how such a blast, and a range of yields from 1 kiloton (kt) to 15 megatons (MT), would be attenuated in New York City, using structural parameters from Northrop/DTRA (1996), blast equations adjusted with empirical data from Glasstone and Dolan (1977), and structural response equations. Attenuation mechanisms include diffraction, kinetic energy in oscillating buildings, plastic deformation, and flying debris. A structural-based attenuation model, tailored to New York’s reinforced concrete and steel-frame buildings, is derived and applied, with energy per unit area tables, comparisons of peak overpressure and dynamic pressure in open terrain versus New York City, and detailed tables for multiple yields.

This report compiles thermal radiation shielding data from five nuclear test reports (WT-717, WT-1317, WT-1351, WT-1417, WT-1621) cited in "Review of City Skyline Nuclear Explosion Thermal Shielding Data with Implications for Firestorm and Nuclear Winter Avoidance." Each entry includes the full report title, inferred authorship, specific quotations, shielding data, and page references from the source document. Additional context is drawn from "Guide to U.S. Atmospheric Nuclear Weapon Effects Data" (DASIAC SR-92-007), confirming report numbering and organizational details. The data, from U.S. nuclear tests between 1955 and 1962, demonstrate significant reductions in thermal radiation behind obstacles, challenging assumptions of widespread firestorms in modern urban environments. A summary table and notes provide context for locating and interpreting the original reports.
