Radioactive Material Area is defined as which of the following?

Radioactive Material Area is defined as which of the following?

• A. Where air is checked for contaminants
• B. Where waste is stored
• C. Where radioactive material is used, stored, and transferred
• D. Where irradiators are located

Answer: (C)

A Radioactive Material Area is defined by the space where radioactive material is used, stored, and transferred. This encompasses the activities that create exposure potential and require radiological controls, not just where air samples are checked or where waste happens to be kept. Air monitoring (that checks for contaminants) is a safety measure used within RMAs, but it doesn’t define the area itself. Storing waste identifies a waste-handling zone, which may or may not coincide with an RMA, so it isn’t the defining criterion. Limiting the definition to the location of irradiators is too narrow, since any area where radioactive material is used, stored, or moved should be considered an RMA.
