Answer to Question 1

primary barrier

Rationale: Primary barriers protect from the useful beam. Primary barriers are any surface that may be struck by the beam, including lead walls and doors.

Answer to Question 2

object-to-image distance

Rationale: Object-to-image receptor distance is OID. Increased OID contributes to part magnification which is destructive to image detail. The general rule is to maintain the part as close to the IR as possible.
