What is the fetal dose limit for a declared pregnant worker for the entire pregnancy?

Explanation:
The key concept is that the fetus has a cumulative exposure limit for the duration of the pregnancy. For a worker who declares pregnancy, the fetus should not receive more than 5 mSv over the entire pregnancy. This limit is set to protect fetal development and remains the total cap regardless of how the exposure is distributed over time. To help manage this, many guidelines also specify a monthly monitoring reference (often about 0.5 mSv per month) and emphasize using time, distance, and shielding to keep doses well below the limit. The other numbers reflect either a monthly cap or higher totals that are not the total pregnancy limit, so they don’t apply as the overall fetal dose for the pregnancy.
