The average annual radiation dose for medical personnel?

• A. 120 (MREM/YR)
• B. 10 (MREM/YR)
• C. 20 (MREM/YR)
• D. 70 (MREM/YR)

Answer: (D)

Occupational exposure in medical settings is kept as low as reasonably achievable, so the average annual dose to medical personnel is typically in the tens of mrem per year. About 70 mrem/year reflects a common, representative average across many facilities, accounting for routine exposure from patient care and imaging while benefiting from shielding, distance, and good work practices. The other values are less representative: 10 or 20 mrem/year are generally too low for the average medical staff across all roles and procedures, while 120 mrem/year is higher than what many facilities report on average. So 70 mrem/year best matches the typical, real-world average.
