Book excerpt: Experiments with nuclear explosions in the ionosphere are known to cause anomalous propagation effects for several days. Shortwave communications are particularly affected with black-out for longer or shorter times. The purpose of this report is to show quantitatively how shortwave and long wave radio propagation are affected by a high altitude nuclear explosion. Two 1 Mt. nuclear explosions at a height of 400 km are assumed, one during day and the other during night.

Available in PDF, EPUB and Kindle. Book excerpt: In a world grappling with the resurgence of nuclear threats and the ongoing exploration of space, this 1976 monograph serves as a vital reminder of the profound impact of human actions on the delicate balance of our planet and the cosmos. It compels us to confront the enduring questions surrounding the responsible use of technology, the pursuit of scientific knowledge, and the preservation of our environment for generations to come. Driven by a primal curiosity to unravel the mysteries of the universe and a deep-seated desire to safeguard our future, we must delve into the lessons of the past to navigate the complex challenges that lie ahead. This monograph provides a comprehensive review of the United States' high-altitude nuclear testing program conducted between 1955 and 1962, focusing on the environmental consequences of these tests. It meticulously details the chronology, locations, and yields of these explosions, while also delving into the complex phenomenology of weapon output interaction with the upper atmosphere. The study illuminates the formation of fireballs, energy partitioning, and debris distribution across vast distances, emphasizing the distinct differences observed at varying altitudes. The monograph examines the impact of these high-altitude tests on various aspects of human activities and the environment. The author, drawing from a wealth of scientific observations and case studies, documents the effects on radio communications, satellite operations, and the creation of artificial radiation belts. The text analyzes the occurrence of phenomena like flash blindness, eyeburn hazards, and disruptions to communication networks, highlighting the severity of these impacts, especially following the high-yield Teak and Orange events. Furthermore, the study addresses concerns regarding the potential effects of high-altitude explosions on weather patterns, the depletion of the ozone layer, and the persistence of radioactive tracers in the stratosphere. While acknowledging the apprehension that initially surrounded these tests, the author concludes by highlighting the substantial scientific insights gained from these high-altitude experiments. He argues that these tests, while not without their drawbacks, ultimately contributed significantly to our understanding of atmospheric physics, plasma dynamics, and the complex interplay between nuclear detonations and the Earth's magnetosphere.

This book was released on 1980 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both satellite radio communications, which travel through the Earth's ionosphere, and high frequency (HF) sky wave circuits, which use the ionosphere as a refracting medium, can be strongly affected by radio wave scintillation. High altitude nuclear explosions cause scintillation (by strongly disturbing the ionosphere) and thus severely degrade satellite radio communications over a large region. Since further atmospheric nuclear tests are banned, a thorough understanding of the physics involved in both the disturbed ionosphere and its interaction with radio waves is necessary in order to design radio communications systems which will operate satisfactorily in a nuclear environment. During the 1980 JASON Summer Study we addressed some aspects of the evolution of ionospheric irregularities following a high altitude nuclear explosion--the radio wave propagation theory being apparently well understood for the satellite link case. In particular, we have worked on irregularity evolution at late times (approx. hours) after an explosion and the impact of early time irregularity structure on late time evolution. We also raise the question of scintillation effects on HF sky wave communications.

Available in PDF, EPUB and Kindle. Book excerpt: This effort was part of a program of research to determine the effects of high-altitude nuclear explosions on HF radio communications, using naturally occurring disturbances to simulate nuclear distrubances. Phase-stable transmissions at 7.366 Mc over a transauroral path from Thule, Greenland and over a mid-latitude path from Fort Monmouth, New Jersey were received at the SRI field site near Palo Alto, California. Both of these paths were paralleled by step-frequency oblique-incidence ionospheric sounders. Power spectra of the received CW signals were computed, enabling the identification of individual ionospheric modes by their separation in Doppler shift. Examples of power spectra of simple and of more complex mode structures, including off-path modes, are given. Statistics of the frequency dispersion and the Doppler shifts of the Thule and Fort Monmouth signals are compiled for selected data in February, March, and June, 1964. Comparisons show that while Doppler shifts for the two paths are similar in magnitude, the frequency dispersion of signals on the transauroral path is about ten times as great as that on the mid-latitude path.

This book was released on 1986 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three ionization zones form during high-altitude nuclear explosions. 1) A short-lived ionization zone in the area of the nuclear explosion; 2) Radioactive cloud hovering over the center of the explosion. The cloud consists of ionized volatile products from the explosion and lingers for several hours or even days; 3) A large zone of increased ionization resulting from gamma and x-ray radiation as well as from neutrons. The zone forms at an altitude of 40 to 70 kilometers and remains for several days. Increased ionization zones have an impact on radio wave propagation and interfere with radio communication as well as the operation of radar stations. Radiation emitted from the increased ionization zone can have an impact on changing the parameters of elements in electronic devices, especially semiconductors. This can in turn interfere with the operation of other equipment, including radio stations, radars, and infrared telescopes, and can also damage this equipment.
