Answer to Question 1

PA

Rationale: The projection of the part describes how the beam travels through the surfaces. The projection of the wrist is PA and the position is ulnar deviation.

Answer to Question 2

100 mR/hr at 1 meter

Rationale: Leakage radiation is defined as radiation escaping from the tube housing and not through the tube window. Equipment guidelines regulate that leakage from the tube housing not exceed 100 mR/hr one meter from the tube.
