This introductory text covers all angles, leading readers from the scientific basics to both "old" and "new" threats from NBC weapons and agents prepared by noncombatant forces, including terrorist organizations. After a look at the history of NBC weapons and their international control, the three classes of nuclear/radiological, biological, and chemical weapons are introduced, focusing on agents and delivery vehicles. There follows an explanation of current methods for the rapid detection of NBC agents and the principles of physical protection of humans and structures. The final parts address more general issues of risk management, preparation and response management, as well as the likely future scenarios that authorities and civil services will be faced with in years to come. For classroom teaching as well as independent study, each chapter contains problems -- with solutions provided in the appendix, as well as a list of recommended reading. With an introduction by John Weimaster, the leading expert on weapons decontamination in the U.S.A.
