What is the occupational dose limit to radiation per year?

The occupational dose limit for radiation exposure in the United States is set by the National Council on Radiation Protection and Measurements (NCRP) and is typically 50 millisieverts (mSv) per year for radiation workers. This limit is intended to minimize health risks while allowing for necessary occupational exposure. For specific groups, such as pregnant workers, the limit is lower, typically around 5 mSv for the duration of the pregnancy. The limits may vary by country and regulatory body, but they generally aim to protect worker health while allowing for safe practices in radiation-related fields.
