Potential actions by terrorist groups span the chemical, biological, radiological, nuclear, and high explosive (CBRNE) threat spectrum . This topic provides guidance for the rapid recognition and initial management of patients exposed to the chemical agents that are most likely to be used in warfare or by terrorists.
Bioterrorism and clinical features and treatment of radiation exposure, including exposure cause by acts of nuclear terrorism, are reviewed separately. (See "Identifying and managing casualties of biological terrorism" and "Clinical features of radiation exposure in children" and "Biology and clinical features of radiation injury in adults" and "Management of radiation exposure in children following a nuclear disaster" and "Treatment of radiation injury in the adult".)
Planning and preparation for field and medical response to weapons of mass destruction are beyond the scope of this topic but are reviewed elsewhere [2-11].
