RSO Training, Emergency Preparedness, and Administration 2

Question 1

An RSO must report a misadministration in nuclear medicine to the NRC when:

Accepted Answer

The administered dose exceeds the prescribed dose by defined thresholds (e.g., >20% for therapeutic doses) or involves the wrong patient/radionuclide

Answer

NRC 10 CFR 35.3045 defines medical events (misadministrations) based on dose thresholds, wrong patient/radionuclide/route criteria; these require 24-hour verbal and 15-day written notification to the NRC.

Question 2

The RSO's primary role during a radiation emergency is to:

Accepted Answer

Provide technical radiation safety expertise, coordinate response actions, and ensure personnel and public protection

Answer

During a radiation emergency, the RSO serves as the technical expert advising on radiation hazards, coordinating protective actions, and interfacing with emergency responders to ensure appropriate radiological controls.

Question 3

How often should an RSO conduct drills or exercises for the radiation emergency response plan?

Accepted Answer

At a frequency specified in the facility's license or plan, typically annually, to verify plan effectiveness and worker preparedness

Answer

NRC license conditions and good practice require periodic drills (commonly annual) to verify that emergency procedures are current, workers are trained, and the plan will work effectively in an actual emergency.

Question 4

License amendments must be obtained from the NRC BEFORE a licensee:

Accepted Answer

Changes the RSO (if required by license condition) or adds new radionuclides/quantities/uses not covered by the existing license

Answer

License amendments are required for changes outside the scope of the existing license, such as adding new radionuclides, new use locations, new use categories, or changing the RSO where the license specifically requires amendment approval.

Question 5

NRC regulations require that a licensee notify the NRC Operations Center within 4 hours of discovering a radiation dose to an individual that:

Accepted Answer

Exceeds 25 rem (250 mSv) TEDE in 24 hours or other immediate notification thresholds

Answer

10 CFR 20.2202 requires immediate (4-hour) NRC notification for doses exceeding 25 rem TEDE, 75 rem to any organ, or 25 rem to the eye, or certain levels in a 24-hour period.
