Estimating the Impact of an Electromagnetic Pulse Caused by a Hypothetical Surface-Level Nuclear Explosion on Urban Critical Infrastructure

This study explores the immediate effects of an electromagnetic pulse (EMP) caused by a hypothetical activation of a nuclear device in an urban area. It aims to conservatively evaluate the impact of the EMP beyond its effective ionization radius by estimating electric field values at specific distances from ground zero using computational analytical simulation and empirical data manipulation. The research outlines steps to address a critical challenge in a catastrophic incident, such as a nuclear attack and subsequent electric power loss. The practical significance of this study is substantial, as it establishes an initial framework for developing protective measures to bolster the resilience of urban areas. To achieve this, the study utilizes equations from former research, simulations supported by HotSpot Health Physics Codes, and equations related to the surface activations of nuclear fission devices. The findings underscore the susceptibility of modern societies to EMPs and highlight the necessity for urban critical infrastructure protective strategies.
