The maximum permissible dose (MPD) for radiation workers is established to ensure their safety and health while they perform their duties in environments where they may be exposed to radiation. The correct answer of 50 mSv is based on guidelines set by regulatory bodies, such as the Occupational Safety and Health Administration (OSHA) and the National Council on Radiation Protection and Measurements (NCRP), which recommend an annual occupational exposure limit.

This limit reflects a balance between allowing workers to perform necessary duties involving radiation while also providing a safeguard against the accumulation of doses that could lead to adverse health effects over time. It’s crucial for radiation workers to monitor and manage their exposure to stay within this established limit.

The other options, like 20 mSv, 30 mSv, and 100 mSv, either fall below the recognized standard for occupational exposure or exceed safe limits set forth by regulatory guidelines. Therefore, the 50 mSv figure marks a significant threshold in occupational health practices that promotes safety without overly restricting radiation work.
