Identify Types of Radiation Incidents (Text Version)

	Obvious in Real Time			Not Obvious in Real Time
	Nuclear Explosion: Weapon or Improvised Nuclear Device	Nuclear Incident at Power Plant / Reactor	Radiological Incident Medical Facility, Transportation, Industrial Facility	RDD: Explosive Device	RDD: Contamination of soil/air/water/food supply	RED: Hidden Radioactive Source
How will it be discovered? Evidence from environmental and/or population observation	Observation of characteristics of nuclear explosion: cloud shape, blast, flash, etc	Evidence of sabotage or accident Routine facility monitoring Explosion internally or externally	Evidence of sabotage or accident Routine facility monitoring	Police/Hazmat investigation of explosion detects radiation	Routine monitoring of concentration of radioactive materials in soil, air, water or food supply Epidemiological surveillance of a population Public health reports leading to a pattern of similar suspicious illnesses	Environmental detectors locate hidden sources outside of expected places, e.g. subway, sports field Public health reports of a pattern of similar suspicious illnesses Unexplained changes in blood counts among people sharing history of being in one (or more) geographic place(s)
Evidence from individual clinical observation	Onset of Acute Radiation Illness (Prodrome)	Occupational worker surveillance as part of facility procedures, badge detection Acute medical trauma or illness	Occupational worker surveillance as part of facility procedures, badge detection Acute medical trauma or illness	Contamination will be considered for all persons in proximity to event identified as a dirty bomb Radiation exposure effects will be sought among the affected victims	Unexplained illnesses Positive Radiation Survey reading in individuals or their body fluids	Unexplained dermatologic condition consistent with radiation burn or radiation dermatitis due to proximity to the radiation source Unexplained drop in blood counts from prolonged exposure Onset of Acute Radiation Syndrome (Prodrome)
