NANTeL Emergency Preparedness and Response 3

Question 1

What is the 'ingestion pathway EPZ' radius typically used for at nuclear power plants?

Accepted Answer

50 miles

Answer

The ingestion pathway EPZ extends approximately 50 miles and addresses contamination of food and water supplies from radioactive deposition.

Question 2

What action does 'sheltering-in-place' provide protection against during a radiological release?

Accepted Answer

Reduction of inhalation dose and some protection from direct radiation by keeping people inside buildings

Answer

Sheltering reduces inhalation exposure and provides partial shielding from the plume by keeping people inside structures with windows and doors closed.

Question 3

Which Federal agency leads the off-site radiological emergency response and coordinates Federal support to state and local governments?

Accepted Answer

Federal Emergency Management Agency (FEMA)

Answer

FEMA coordinates overall Federal emergency response under the National Response Framework and evaluates off-site radiological emergency planning adequacy.

Question 4

The Emergency Alert System (EAS) is used during nuclear emergencies primarily to:

Accepted Answer

Alert the public and provide protective action instructions via radio and TV broadcasts

Answer

EAS broadcasts emergency notifications and protective action instructions (e.g., evacuate or shelter) to the public through radio, television, and wireless alerts.

Question 5

What is a 'source term' in the context of nuclear emergency dose assessment?

Accepted Answer

The quantity and type of radioactive material released or potentially released to the environment

Answer

A source term quantifies the radionuclide inventory, timing, and magnitude of a release, forming the input to atmospheric dispersion and dose calculations.
