If a monitor is lost, how is the radiation dose estimated?

Explanation:
When a monitor is lost, you can’t access the actual recorded dose for the missing period, so you need to reconstruct that exposure from available information. The most reasonable approach is for the physicist to estimate the missing dose by averaging the worker’s last six months of monitor readings. This uses recent exposure history to project the missing period, smoothing out short-term fluctuations and providing a defensible, auditable estimate. It’s better than ignoring the data, replacing it with no data, or assuming zero, because those options would underrepresent the worker’s true exposure and could conflict with dose-record requirements. If needed, the estimate can include an acknowledged uncertainty to reflect any remaining variability.
