The objective was to determine the velocity and distance of translation of anthropomorphic dummies and equivalent spheres caused by blast winds. The primary technique for recording the movement of these objects was photo-triangulation. Analysis of the films obtained thereby gave the velocity and distance in the case of shot 1. In shot 2, the field of view was obscured by smoke (perhaps dust too) before any motion could be recorded by the cameras. The secondary technique (applicable to certain of the equivalent spheres) was to have the spheres impelled into missile traps. The resultant penetration provides a means for determining the velocity at the time of impact. Analysis of the results from both the primary and secondary techniques is expected to provide some of the information identified in the objective.

A total of 455 mice, rats, guinea pigs and rabbits were subjected to impact at velocities ranging between 25 ft/sec and 51 ft/sec. The desired velocities were generated by allowing the animals to free-fall from various heights to a flat concrete pad. The ventral surface of each animal was the area of impact. Probit analyses of the 24-hr mortality data yielded LD50 impact velocities with 95 per cent confidence limits as follows: mouse, 39.4 (37.4-42. 0) ft/sec; rat, 43.5 (42.0 - 44.8) ft/sec; guinea pig, 31.0 (30.0 - 31.9) ft/ sec. The LD50 figures for the mouse and rat were significantly higher, statistically, than those for the guinea pig and rabbit. The small spread in the LD50 values suggested little variation in the tolerance of biological systems to impact. Further, the steepness of the mortality curves indicated a narrow survival range to impact. Extrapolation of the experimental data to the 70 kg animal yielded a predicted LD50 impact velocity of 26 ft/sec (18 mph). Literature relevant to the human case was reviewed and the tentative applicability of the predicted figures to adult man was discussed. (Author).

The shelters also contained static and dynamic pressure gauges, radiation detectors, telemetering devices, and, in one test, air-temperature measuring gauges, radiation detectors, telemetering devices, and, in one test, air-temperature measuring instruments, dust-collecting trays, and eight pigs for the biological assessment of thermal effects. One dog was severely injured from tertiary blast effects associated with a maximal dynamic pressure (Q) of 10.5 psi, and one was undamaged with a maximal Q of 2 psi. Primary blast effects resulting from peak overpressures of 30.3, 25.5, 9.5, and 4.1 psi were minimal. The mortality was 19 per cent of the mice exposed to a peak pressure of 30.3 psi and 5 and 3 per cent of the guinea pigs and mice exposed to a peak pressure of 25.5 psi. Many of the rabbits, guinea pigs, and mice sustained slight lung hemorrhages at maximum pressures of 25.5 and 30.3 psi.

Explosion and Blast-Related Injuries is an authoritative text that brings together diverse knowledge gained from both the experience of clinicians treating blast casualties and the insights of scientists obtained from research and modeling of blast exposures. By providing information on explosion and blast injury patterns, as well as the mechanism of blast-induced injuries, it is a useful reference for both physicians and researchers. With contributions by experts from around the globe, the book covers topics such as the epidemiology of blast and explosion injury, pathology and pathophysiology, and the modeling and mechanism of injury. Finally, this book might stimulate additional studies into ways to improve our current mass casualty response systems. * Contains contributions from experts who had first hand experience dealing with explosion and blast injuries. * Provides a diverse global experience derived from both military operations and terrorist attacks in civilian settings from the US, Europe and the Middle East. * Covers such topics as epidemiology of blast and explosion injury, pathology and pathophysiology, modeling and mechanism of injury, and finally presents the global experiences of blast injury and mass casualty management.

This book compiles a variety of experimental data on blast waves. The book begins with an introductory chapter and proceeds to the topic of blast wave phenomenology, with a discussion on Rankine-Hugoniot equations and the Friedlander equation, used to describe the pressure-time history of a blast wave. Additional topics include arrival time measurement, the initiation of detonation by exploding wires, a discussion of TNT equivalency, and small scale experiments. Gaseous and high explosive detonations are covered as well. The topics and experiments covered were chosen based on the comparison of used scale sizes, from small to large. Each characteristic parameter of blast waves is analyzed and expressed versus scaled distance in terms of energy and mass. Finally, the appendix compiles a number of polynomial laws that will prove indispensable for engineers and researchers.

A nuclear attack on a large U.S. city by terrorists-even with a low-yield improvised nuclear device (IND) of 10 kilotons or less-would cause a large number of deaths and severe injuries. The large number of injured from the detonation and radioactive fallout that would follow would be overwhelming for local emergency response and health care systems to rescue and treat, even assuming that these systems and their personnel were not themselves incapacitated by the event. The United States has been struggling for some time to address and plan for the threat of nuclear terrorism and other weapons of mass destruction that terrorists might obtain and use. The Department of Homeland Security recently contracted with the Institute of Medicine to hold a workshop, summarized in this volume, to assess medical preparedness for a nuclear detonation of up to 10 kilotons. This book provides a candid and sobering look at our current state of preparedness for an IND, and identifies several key areas in which we might begin to focus our national efforts in a way that will improve the overall level of preparedness.
