Responding to Chemical and Radiological Disasters – A Self-Paced Training Course is an interactive CD training tool targeted at public health and healthcare professionals. It is organized along two basic learning tracks starting with the basics of radiation and toxicology, followed by the role of public health in radiological disasters, and more detailed training on radiological and chemical incidents. All-hazards modules introducing mass triage, decontamination and the use of personal protective equipment are also included. The CD contains supplemental videos and additional training resources from the Centers for Disease Control and Prevention and OSHA.
