Book Description
Shielded special nuclear material (SNM) is very difficult to detect and new technologies are needed to clear alarms and verify the presence of SNM. High-energy photons and neutrons can be used to actively interrogate for heavily shielded SNM, such as highly enriched uranium (HEU), since neutrons can penetrate gamma-ray shielding and gamma-rays can penetrate neutron shielding. Both source particles then induce unique detectable signals from fission. In this LDRD, we explored a new type of interrogation source that uses low-energy proton- or deuteron-induced nuclear reactions to generate high fluxes of mono-energetic gammas or neutrons. Accelerator-based experiments, computational studies, and prototype source tests were performed to obtain a better understanding of (1) the flux requirements, (2) fission-induced signals, background, and interferences, and (3) operational performance of the source. The results of this research led to the development and testing of an axial-type gamma tube source and the design/construction of a high power coaxial-type gamma generator based on the 11B(p, [gamma])12C nuclear reaction.

Book Description
"Nuclear terrorism is such a disturbing prospect that we shy away from its details. Yet as a consequence, we fail to understand how best to defeat it. Michael Levi takes us inside nuclear terrorism and behind the decisions a terrorist leader would be faced with in pursuing a nuclear plot. Along the way, Levi identifies the many obstacles, large and small, that such a terrorist scheme might encounter, allowing him to discover a host of ways that any plan might be foiled. Surveying the broad universe of plots and defenses, this accessible account shows how a wide-ranging defense that integrates the tools of weapon and materials security, law enforcement, intelligence, border controls, diplomacy, and the military can multiply, intensify, and compound the possibility that nuclear terrorists will fail. Levi draws from our long experience with terrorism and cautions us not to focus solely on the most harrowing yet most improbable threats. Nuclear terrorism shares much in common with other terrorist threats--and as a result, he argues, defeating it is impossible unless we put our entire counterterrorism and homeland security house in order. As long as we live in a nuclear age, no defense can completely eliminate nuclear terrorism. But this book reminds us that the right strategy can minimize the risks and shows us how to do it."

Book Description
A handbook for scholars, students, policy makers, journalists, and peace and environmental activists.A handbook for scholars, students, policy makers, journalists, and peace and environmental activists, Nuclear Wastelands provides concise histories of the development of nuclear weapons programs of every declared and de facto nuclear weapons power, as well as detailed surveys of the health and environmental effects of this development both in these countries and in non-nuclear nations involved in nuclear weapons testing and uranium mining. Among the more obvious but largely deferred costs of the Cold War are those related to the management of radioactive waste. The world is burdened with thousands of unwanted nuclear devices and mounting surpluses of weapons-grade plutonium and enriched uranium. In addition, the process of weapons production and testing has left many lands, aquifers, rivers, lakes, and seas contaminated by a multitude of weapons-related poisons. This book follows the production process step by step and country by country from uranium mining to the final assembly and storage of weapons, analyzing the potential hazards of each step and compiling the most complete information available on the actual health and environmental effects, in each country involved. Nuclear Wastelands includes a wealth of information that has only recently come to light, particularly on the nuclear weapons program of the former Soviet Union. It also features critical analyses of official public communications concerning the health and environmental consequences of nuclear weapons production, bringing to light governmental secrecy and outright deception that have led to the subversion of democratic principles, and have camouflaged the damage done to the very people and lands the weapons were meant to safeguard.

Book Description
The Four Faces of Nuclear Terrorism, a new book from the Center for Nonproliferation Studies, assesses the motivations and capabilities of terrorist organizations to acquire and use nuclear weapons, to fabricate and and detonate crude nuclear explosives, to strike nuclear power plants and other nuclear facilities, and to build and employ radiological weapons or "dirty bombs."

Book Description
An authoritative study of the dangers nations face today from weapons of mass destruction and the successes and failures of international nonproliferation efforts. This proliferation atlas documents with maps, charts, and graphs the spread of nuclear, chemical, and biological weapons and missile delivery systems. The book describes the weapons and the regimes that try to control them; it also details the countries that have, want, or have given up weapons of mass destruction. Deadly Arsenals provides the most up-to-date and comprehensive assessment available on the subject and is a valuable resource for policymakers, scholars, students, and the media.
