Terrorism AwarenessQuestion 194 of 200
The three fundamental radiological-protection principles for limiting exposure are:
a.Eat, Drink, Sleep
b.Stop, Look, Listen
c.Detect, Identify, Document
d.Time (minimize), Distance (maximize), Shielding (use barriers)
Explanation
Time, Distance, and Shielding are the three core principles of radiation protection adopted by the NRC, FEMA, and ICRP. Minimize Time of exposure (dose is cumulative); Maximize Distance (intensity falls with the inverse square — doubling distance quarters intensity); use Shielding (concrete, lead, even thick walls reduce dose) between you and the source. For a security officer responding to a suspected radiological incident (e.g., dirty-bomb concern), evacuating upwind, isolating the area, increasing distance, and notifying 911 / hazmat are the immediate priorities.
