What is the primary radiation hazard posed by a Radiological Dispersal Device (RDD or 'dirty bomb')?
Answer: Widespread contamination requiring cleanup and potential inhalation hazard
RDDs primarily create contamination hazards and psychological impact; actual radiation doses are generally far lower than from a nuclear detonation.
In the initial response to a suspected RDD incident, what should be the first responder's top priority?
Answer: Life safety — treat injured and secure a perimeter
Life safety always takes priority in emergency response; radiation hazards are assessed after immediate life-threatening injuries are stabilized.
Which radiation survey instrument is most appropriate for initial radiological field assessment at an RDD incident scene?
Answer: Geiger-Mueller detector with a rate meter
A GM detector with a rate meter provides immediate, real-time radiation readings suitable for rapid field assessment at an RDD incident.
What is the primary goal of establishing a 'hot zone' at a radiological incident scene?
Answer: To contain contamination and limit exposure of response personnel
The hot zone is established to contain contamination and restrict entry to trained, properly equipped personnel, thereby limiting total dose to responders.
EPA Protective Action Guides (PAGs) recommend considering sheltering or evacuation when projected doses from a nuclear/radiological incident would exceed:
Answer: 10 mSv (1 rem)
EPA PAGs recommend considering sheltering or evacuation when projected early-phase doses exceed 10 mSv (1 rem) from the plume.
Which organization publishes the Protective Action Guides (PAGs) used in the US for radiological emergency response decisions?
Answer: EPA (Environmental Protection Agency)
The EPA publishes the Protective Action Guides that establish dose thresholds for emergency protective actions like sheltering, evacuation, and food restrictions.
