The thawing of the Cold War has removed a nuclear threat that hung over the world for decades, but that is no reason to drop one's guard. Smaller and more belligerent states now have nuclear, biological and chemical capabilities, and the will to use them. In recent years, terrorist groups have been using chemical agents, and the time cannot be far off when a terrorist organization makes use of a nuclear threat. This volume provides type-by-type coverage of the biological and chemical agents which are continually debated on the weapons of mass destruction. It includes details of the means of delivery of NBC weapons and descriptions of the protective equipment available for the emergency services.
