Nuclear Regulatory Commission – Checklist to Provide a Basis for Confidence that Radioactive Materials will?

Step – 1 – Initial Screening – When asked whether an applicant is a known entity or unknown entity, how does the NRC define known or unknown?

1. If a Physician is an Authorized Physician User on a license and decides to open a Nuclear
Medicine Clinic, would he or she be considered an known or unknown entity?

2. An application for a new RAM license submitted by a well know consultant.

3. If a Physician applies for a RAM license and has never had one before, but he has
a State Medical License, would he or she be considered a known or unknown entity.

I spent hours searching the NRC website trying to find simple NRC definitions of known entities and
unknown entities. If you know where these definitions are on the NRC website please tell me.

Thank you
