The average annual radiation dose for university radiation worker?

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

Answer: (A)

The key idea is that university radiation workers generally receive very small occupational doses because of shielding, strict access controls, and the ALARA principle. The average amount of radiation these workers accumulate in a year is typically around 10 mrem, which is about 0.1 mSv. This is a tiny fraction of the regulatory occupational limit (50 mSv per year, or 5 rem) and well below what most people think of as a year’s exposure from all sources. So, among common values, 10 mrem per year best represents the average for a university setting.
