The maximum weekly permitted equivalent dose for a controlled area must not exceed

Question

Quizplus · Accepted Answer

The maximum weekly permitted equivalent dose for a controlled area is typically set to ensure safety and minimize radiation exposure risks. The standard limit is 1 mSv (millisievert) per year for the general public, which translates to approximately 0.02 mSv per week. However, for occupational exposure in controlled areas, higher limits are allowed. The choice of 1 mSv in the options seems to be a misinterpretation, as it is closer to the annual limit for the general public rather than a weekly limit for occupational exposure. The correct occupational limits are higher, but none of the other options provided (100 mSv, 20 mSv, 2 mSv) accurately represent a weekly limit. The most accurate guidance comes from the International Commission on Radiological Protection (ICRP) and national regulations, which typically set occupational exposure limits at 20 mSv per year, averaged over defined periods of 5 years, with no more than 50 mSv in any single year. Therefore, the question seems to contain a misunderstanding of the limits, and based on the provided options, none accurately reflects typical weekly permitted doses in controlled areas according to standard guidelines.
