• A. ALARA stands for As Low As Readily Achievable; protective measures include using the highest feasible exposure to ensure image quality.
• B. ALARA stands for As Low As Reasonably Achievable; protective measures include using the lowest feasible exposure, shielding (lead apron and thyroid collar), proper technique to minimize repeats, beam collimation and operator distance.
• C. ALARA stands for All Radiation Always Reduces Any risk At All times; protective measures include shielding.
• D. ALARA stands for As Large As Reasonably Achievable; protective measures include maximizing exposure.

Answer: (B)
