NRRPT Emergency Response and Decontamination 5

Question 1

Which federal agency has primary responsibility for coordinating federal radiological emergency response under the National Response Framework?

Accepted Answer

Federal Emergency Management Agency (FEMA)

Answer

FEMA coordinates overall federal emergency response under the NRF, with NRC and DOE providing technical radiological support.

Question 2

When performing whole-body counting on a potentially internally contaminated individual, the purpose is to:

Accepted Answer

Detect and quantify gamma-emitting radionuclides in the body

Answer

Whole-body counters detect gamma radiation emitted from internally deposited radionuclides to estimate internal contamination levels.

Question 3

The 'ingestion exposure pathway' EPZ around nuclear power plants extends to approximately what distance?

Accepted Answer

50 miles

Answer

The ingestion pathway EPZ extends to approximately 50 miles to address contamination of food, water, and agricultural products.

Question 4

During mass decontamination of ambulatory victims, which body areas should receive priority attention due to highest contamination retention?

Accepted Answer

Hair, face, hands, and skin folds where contamination accumulates

Answer

Hair, facial features, and skin folds retain contamination most effectively and pose the highest risk of internal uptake if not prioritized.

Question 5

A worker's bioassay results show 10 times the ALI of Cs-137 in the body. The immediate health physics action is to:

Accepted Answer

Administer Prussian Blue to enhance Cs-137 excretion and remove the worker from further exposure

Answer

Prussian Blue is the FDA-approved treatment to accelerate Cs-137 elimination by trapping it in the gut; the worker must also be removed from further exposure.
