Answer to Question 1

100 mR/h

Rationale: NCRP regulations state the leakage radiation from the tube should not exceed 100 mR/h at a distance of 1 meter from the tube.

Answer to Question 2

AP ankle with inversion stress

Rationale: The image represents an AP projection of the ankle with inversion stress applied. Inversion stress inverts the foot and plantar surface toward the midline. This will evaluate the lateral region of the ankle.
