Available in PDF, EPUB and Kindle. Book excerpt: Samples of 6 explosive compounds (TNT, tetryl, NC, ROX, HMX, and PETN) and 4 explosive mixtures were exposed to the neutron and gamma radiation from a power reactor at integrated flux levels of approximately 1015 and 3 x 10/ sup 16/ n/cm2. The irradiated samples were subjected to a variety of chemical and physical tests. Only minor effects were noted at the lower exposure level, but extensive deterioration of the aliphatic and and heterocyclic compounds occurred in the 1016 run. G-values of 2.9 and 1.4 were obtained for the destruction of ROX and HMX, respectively. An experiment in which samples of 5 explosive compounds and mixtures were exposed to a radiation burst from the Godiva II critical assembly is described. No significant damage to the samples resulted from this exposure. (auth).

Book excerpt: The dimensional changes and loss of weight resulting when selected conventional and fluoroexplosives are exposed to doses of Co(60) gamma irradiation up to 2 x 10 to the 9th power rad have been observed. The two heterocyclic compounds which were used in these studies, RDX and HMX, behaved similarly and exhibited the greatest dimensional and weight loss changes of all the materials studied. The conventional aromatic compounds, TNT, Tetryl, TNB and DATB, exhibited similar behavior, which was significantly different from that of the two heterocyclic compounds. The radiation stability of these compounds was also significantly greater than that for the heterocyclic compounds. As a group, the deformation of the fluoro-derivatives followed no similar pattern. Their weight-loss stability was significantly better than that of the heterocyclic compounds, but was exceeded by the aromatic compounds.

Available in PDF, EPUB and Kindle. Book excerpt: A group of eleven explosive materials in powder and pellet form were subjected to Co60 gamma radiation and the results are tabulated and discussed. Teh explosives were studied using weight loss, dimensional change, vacuum stability, DTA, TGA, infrared spectra, melting point, impact sensitivity, explosion temperature and rates of detonation as a function of total gamma exposure up to and including levels of ten to the ninth power R. Based on this work, a damage threshold as a function of total gamma dose was determined for each material. The results indicate that the capability of the explosives studied to withstand Co60 gamma radiation decreases in the following order: TACOT = or> TATB = or> DATB = or> HMX = or> Tetryl = or> TNB = or> TNT = or> RDX = or> PETN> NGu> BaN6.

This book was released on 2005-10-06 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underground facilities are used extensively by many nations to conceal and protect strategic military functions and weapons' stockpiles. Because of their depth and hardened status, however, many of these strategic hard and deeply buried targets could only be put at risk by conventional or nuclear earth penetrating weapons (EPW). Recently, an engineering feasibility study, the robust nuclear earth penetrator program, was started by DOE and DOD to determine if a more effective EPW could be designed using major components of existing nuclear weapons. This activity has created some controversy about, among other things, the level of collateral damage that would ensue if such a weapon were used. To help clarify this issue, the Congress, in P.L. 107-314, directed the Secretary of Defense to request from the NRC a study of the anticipated health and environmental effects of nuclear earth-penetrators and other weapons and the effect of both conventional and nuclear weapons against the storage of biological and chemical weapons. This report provides the results of those analyses. Based on detailed numerical calculations, the report presents a series of findings comparing the effectiveness and expected collateral damage of nuclear EPW and surface nuclear weapons under a variety of conditions.

This book was released on 2004-05-14 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Existing and Potential Standoff Explosives Detection Techniques examines the scientific techniques currently used as the basis for explosives detection and determines whether other techniques might provide promising research avenues with possible pathways to new detection protocols. This report describe the characteristics of explosives, bombs, and their components that are or might be used to provide a signature for exploitation in detection technology; considers scientific techniques for exploiting these characteristics to detect explosives and explosive devices; discusses the potential for integrating such techniques into detection systems that would have sufficient sensitivity without an unacceptable false-positive rate; and proposes areas for research that might be expected to yield significant advances in practical explosives and bomb detection technology in the near, mid, and long term.

This book was released on 1998-06-27 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to the rising concern of the American public over illegal bombings, the Bureau of Alcohol, Tobacco, and Firearms asked the National Research Council to examine possible mechanisms for reducing this threat. The committee examined four approaches to reducing the bombing threat: addition of detection markers to explosives for pre-blast detection, addition of identification taggants to explosives for post-blast identification of bombers, possible means to render common explosive materials inert, and placing controls on explosives and their precursors. The book makes several recommendations to reduce the number of criminal bombings in this country.

Available in PDF, EPUB and Kindle. Book excerpt: Detection and quantification of trace chemicals is a major thrust of analytical chemistry. In recent years much effort has been spent developing detection systems for priority pollutants. Less mature are the detections of substances of interest to law enforcement and security personnel:in particular explosives. This volume will discuss the detection of these, not only setting out the theoretical fundamentals, but also emphasizing the remarkable developments in the last decade. Terrorist events—airplanes blown out of the sky (PanAm 103 over Lockerbie) and attacks on U.S. and European cities (Trade Center in New York and the Murrah Federal Building in Oklahoma City, railways in London and Madrid)--emphasize the danger of concealed explosives. However, since most explosives release little vapor, it was not possible to detect them by technology used on most organic substances. After PanAm 103 was downed over Scotland, the U.S. Congress requested automatic explosive detection equipment be placed in airports. This volume outlines the history of explosive detection research, the developments along the way, present day technologies, and what we think the future holds. Written by experts in the field who set out both the scientific issues and the practical context with authority Discusses and describes the threat Describes the theoretical background and practical applications of both trace and bulk explosives detection

Available in PDF, EPUB and Kindle. Book excerpt: This newly published book is intended for dual use as a textbook for students in radiation shielding courses and a reference work for shielding practitioners. It emphasizes the principles behind techniques used in various aspects of shield analysis and presents these principles in many different contexts. This approach is intended to provide a strong base of understanding in order to facilitate use of the large shielding codes that have come to dominate shielding design and analysis. An assumption is made that the reader has an understanding of mathematics through basic calculus and vector analysis as well as a knowledge of the nuclear physics of radioactive decay. For most chapters, problem sets are provided.
