Available in PDF, EPUB and Kindle. Book excerpt: Monitoring Underground Nuclear Explosions focuses on the checking of underground nuclear explosions, including the Comprehensive Test Ban Treaty (CTB), seismological stations, earthquake-source models, and seismicity. The publication first elaborates on test-ban negotiations, nuclear explosions, seismological background, and explosions and earthquakes as seismic sources. Concerns cover comparison between explosion-source and earthquake-source models, theoretical calculation of seismic waves, earth structure, seismicity, nuclear test activities, bomb designs, and disarmament treaties. The manuscript then tackles seismological stations, detection, event definition and location, depth estimation, and identification. Topics include multistation discriminants, statistical aspects, long-period and short-period signals, near distances, location by a network of stations, international data exchange, station detection capabilities, and station networks. The book examines the monitoring of a comprehensive test-ban treaty, nonseismological identification, evasion, peaceful nuclear explosions, and yield estimation. The text is a dependable reference for researchers interested in the monitoring of underground nuclear explosions.

Book excerpt: This document lists chronologically and alphabetically by name all nuclear tests and simultaneous detonations conducted by the United States from July 1945 through September 1992. Two nuclear weapons that the United States exploded over Japan ending World War II are not listed. These detonations were not "tests" in the sense that they were conducted to prove that the weapon would work as designed (as was the first test near Alamogordo, New Mexico on July 16, 1945), or to advance nuclear weapon design, or to determine weapons effects, or to verify weapon safety as were the more than one thousand tests that have taken place since June 30,1946. The nuclear weapon (nicknamed "Little Boy") dropped August 6,1945 from a United States Army Air Force B-29 bomber (the Enola Gay) and detonated over Hiroshima, Japan had an energy yield equivalent to that of 15,000 tons of TNT. The nuclear weapon (virtually identical to "Fat Man") exploded in a similar fashion August 9, 1945 over Nagaski, Japan had a yield of 21,000 tons of TNT. Both detonations were intended to end World War II as quickly as possible. Data on United States tests were obtained from, and verified by, the U.S. Department of Energy's three weapons laboratories -- Los Alamos National Laboratory, Los Alamos, New Mexico; Lawrence Livermore National Laboratory, Livermore, California; and Sandia National Laboratories, Albuquerque, New Mexico; and the Defense Threat Reduction Agency. Additionally, data were obtained from public announcements issued by the U.S. Atomic Energy Commission and its successors, the U.S. Energy Research and Development Administration, and the U.S. Department of Energy, respectively.

Download or read book 100 Suns written by Michael Light and published by Knopf. This book was released on 2013-04-03 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Between July 1945 and November 1962 the United States is known to have conducted 216 atmospheric and underwater nuclear tests. After the Limited Test Ban Treaty between the United States and the Soviet Union in 1963, nuclear testing went underground. It became literally invisible—but more frequent: the United States conducted a further 723 underground tests, the last in 1992. 100 Suns documents the era of visible nuclear testing, the atmospheric era, with one hundred photographs drawn by Michael Light from the archives at Los Alamos National Laboratory and the U.S. National Archives in Maryland. It includes previously classified material from the clandestine Lookout Mountain Air Force Station based in Hollywood, whose film directors, cameramen and still photographers were sworn to secrecy. The title, 100 Suns, refers to the response by J.Robert Oppenheimer to the world’s first nuclear explosion in New Mexico when he quoted a passage from the Bhagavad Gita, the classic Vedic text: “If the radiance of a thousand suns were to burst forth at once in the sky, that would be like the splendor of the Mighty One . . . I am become Death, the destroyer of worlds.” This was Oppenheimer’s attempt to describe the otherwise indescribable. 100 Suns likewise confronts the indescribable by presenting without embellishment the stark evidence of the tests at the moment of detonation. Since the tests were conducted either in Nevada or the Pacific the book is simply divided between the desert and the ocean. Each photograph is presented with the name of the test, its explosive yield in kilotons or megatons, the date and the location. The enormity of the events recorded is contrasted with the understated neutrality of bare data. Interspersed within the sequence of explosions are pictures of the awestruck witnesses. The evidence of these photographs is terrifying in its implication while at same time profoundly disconcerting as a spectacle. The visual grandeur of such imagery is balanced by the chilling facts provided at the end of the book in the detailed captions, a chronology of the development of nuclear weaponry and an extensive bibliography. A dramatic sequel to Michael Light’s Full Moon, 100 Suns forms an unprecedented historical document.

Available in PDF, EPUB and Kindle. Book excerpt: Three authoritative reports provide unique information about nuclear weapons testing and the verification of nuclear nonproliferation treaties: (1) The Containment of Underground Nuclear Explosions, (2) Seismic Verification of Nuclear Testing Treaties, (3) Environmental Monitoring for Nuclear Safeguards. The Containment of Underground Nuclear Explosions - At a time of continued underground nuclear bomb tests, an assessment of the safety of the process led to this report. This special report reviews the safety of the nuclear testing program and assesses the technical procedures used to test nuclear weapons and ensure that radioactive material produced by test explosions remains contained underground. An overall evaluation considers the acceptability of the remaining risk and discusses reasons for the lack of public confidence. Seismic Verification of Nuclear Testing Treaties - Like an earthquake, the force of an underground nuclear explosion creates seismic waves that travel through the Earth. A satisfactory seismic network to monitor such tests must be able to both detect and identify seismic signals in the presence of "noise," for example, from natural earthquakes. In the case of monitoring a treaty that limits testing below a certain size explosion, the seismic network must also be able to estimate the size with acceptable accuracy. All of this must be done with an assured capability to defeat adequately any credible attempt to evade or spoof the monitoring network. This report addresses the issues of detection, identification, yield estimation, and evasion to arrive at answers to the two critical questions: Down to what size explosion can underground testing be seismically monitored with high confidence? How accurately can the yields of underground explosions be measured? Environmental Monitoring for Nuclear Safeguards - To assure that states are not violating their Non-Proliferation Treaty commitments, the International Atomic Energy Agency (IAEA) must also verify that states do not possess covert nuclear facilities-a mission that prior to the 1991 Gulf War, it had neither the political backing nor the resources to conduct. In the report, OTA concluded that providing the IAEA with the resources, the information, and the political support it needs to look for such sites may turn out to be the most important aspect of a reinvigorated safeguards regime. The IAEA recognizes the importance of this new mission and is in the process of assuming it. One of the tools it is exploring to provide some indication of the presence of secret, or undeclared, nuclear activities and facilities is environmental monitoring. Modern sampling and analysis technologies provide powerful tools to detect the presence of characteristic substances that are likely to be emitted by such illicit activities. This background paper examines the prospects for such technologies to improve nuclear safeguards. It concludes that environmental monitoring can greatly increase the ability to detect undeclared activity at declared, or known, sites, and it can significantly increase the chances of detecting and locating undeclared sites.

Book excerpt: Project 1.7 of Operation TEAPOT was concerned with the measurement of surface and subsurface effects of an underground explosion of a 1.2-kt nuclear burst (Shot 7). The measurements included free-field earth and airblast effects, as well as loading on underground structural devices. This report deals with the presentation and analysis of the free-field data only; the structural data have been transmitted to the appropriate agencies for their analysis. From the 76 channels installed on TEAPOT Shot 7, 75 usable records were obtained. The free-field quantities measured include air-blast pressure, earth acceleration, earth stress and strain, and permanent earth displacement. The results are discussed by phenomenon and, in each case, the TEAPOT data are compared with pretest predictions. Also, where data are available, comparisons are made with previous underground nuclear test results. Some aspects of seismology and soil mechanics as applied to underground explosion phenomena are presented and, finally, the most pertinent high explosives results from subsequent tests conducted at the TEAPOT location are summarized.

Available in PDF, EPUB and Kindle. Book excerpt: To achieve successful solutions to the problems resulting from local, distant and global radioactive fallout after nuclear explosions and accidents and to achieve successful retrospective analyses of the radiation conditions from recent observations, certain information is needed: the distribution of the exposure dose rate in the atmosphere and in a country; the distribution of radionuclides in natural environments and the nuclide composition of the radioactive fallout; the features of formation of the aerosol particle-carriers of the radioactivity and of the nuclide distribution of the particles of different sizes formed under different conditions; the processes involved in the migration of radioactive products in different zones and environments; the external and internal effects of nuclear radiation on human beings.This monograph is devoted to a number of these problems, namely, to studies of the radioactive fallout composition, the formation of the aerosol particles that transport the radioactive products and to the analysis of the external radiation doses resulting from nuclear explosions and/or accidents. Problems of restoration and rehabilitation of contaminated land areas are also touched upon in the monograph. To solve such problems one requires knowledge of the mobility of radionuclides, an understanding of their uptake by plants, their transportation within the food chain and finally their uptake by animal and/or human organisms.The results of many years of study of radioactive fallout from atmospheric and underground nuclear explosions and accidents are summarized in this book. It is intended for various specialists - geophysicists, ecologists, health experts and inspectors, as well as those who are concerned with radioactive contamination of natural environments.
