NRRPT Emergency Response and Decontamination 4

Question 1

When establishing an emergency decontamination corridor, water runoff control is important primarily to prevent:

Accepted Answer

Spread of radioactive contamination to uncontrolled areas

Answer

Uncontrolled runoff can transport radioactive material beyond the contamination zone, expanding the contaminated area.

Question 2

Which of the following best describes a 'dirty bomb' (RDD) from a radiation protection standpoint?

Accepted Answer

A conventional explosive combined with radioactive material designed to disperse contamination

Answer

An RDD uses conventional explosives to disperse radioactive material; its primary effect is contamination and psychological impact, not nuclear yield.

Question 3

Potassium iodide (KI) administration in a radiological emergency protects which organ by what mechanism?

Accepted Answer

Thyroid, by saturating iodine uptake to block radioiodine absorption

Answer

KI saturates thyroid iodine receptors with stable iodine, preventing uptake of inhaled or ingested radioactive iodine isotopes.

Question 4

In the Incident Command System (ICS) used during radiological emergencies, the Radiation Protection Officer typically reports to which position?

Accepted Answer

Safety Officer

Answer

The Radiation Protection Officer functions as a technical specialist and typically supports the Safety Officer in the ICS structure.

Question 5

A nuclear power plant declares a 'General Emergency.' What immediate protective action recommendation is typically made for the public within 2 miles?

Accepted Answer

Evacuate immediately

Answer

A General Emergency implies imminent or actual substantial release; immediate evacuation within 2 miles (the inner EPZ) is the standard initial protective action.
