Terrorism Is and always has been . . . a form of warfare.
CASUALTY-PRODUCING ABILITIES Selective Targets
Terrorism Both the target and the type of weapon used are chosen for a purpose.
Achieving victory in every battle is not absolute perfection; neutralizing an adversary’s force without battle is absolute perfection. --Sun Tzu, The Art of War
Threat Levels Imminent Threat Alert Warns of a credible, specific, and impending terrorist threat against the United States. Elevated Threat Alert Warns of a credible terrorist threat against the United States.

Introduction to Radiation • Review of Ionizing Radiation • Review or Introduction to Dosimetry • Deployment of the UltraRadiac • Responding to a Dosimeter Alarm
Nuclear/Radiological Incident General Information • Radiation can be detected with meters • Unlikely to find high levels distant from the source • Use meters to determine isolation area • Victims should not be sick or symptomatic on the scene • Exposure only does not require immediate gross decontamination
Types of Ionizing Radiation Provided by the Department of Energy, NsTec
Potential Radioactive Sources • Use of radiological material in a terrorist attack. • Radiological Dispersal Device (RDD) • Radiological Exposure Device (RED) • Radiopharmaceuticals used in medicine • Industrial sources • Naturally occurring
Nuclear/Radiological Incident • Time, distance, and shielding are appropriate self-protective measures • Equipment Pancake Detector RadWatch Dosimeter Canberra UltraRadiac RadiationMonitor FLIR nanoRaider Ludlum Response Kit
Radwatch • You will be issued a radwatch at the time of deployment. • The radwatch will measure your radiation absorbed dose during the deployment and must be worn entire time. • The radwatch may be read during the deployment if needed.
Units of Measure Roentgen (R) – ionization of air by radiation energy R per hour (R/hr) is used on radiation survey meters Radiation Absorbed Dose (Rad) – a unit for measuring absorbed dose in any material
Units of Measure For gamma and x ray radiation, a common “conversion factor” between exposure, absorbed dose, and dose equivalent is: 1 R = 1 rad = 1 rem
