What is the annual occupational dose limit in mSv?

The annual occupational dose limit for radiation workers is set at 50 mSv according to guidelines from organizations such as the National Council on Radiation Protection and Measurements (NCRP) and the International Commission on Radiological Protection (ICRP). This limit is designed to protect workers from the potential harmful effects of ionizing radiation over the course of their careers.

The 50 mSv limit considers both the cumulative exposure and the long-term risks associated with radiation. Maintaining this threshold helps ensure that radiation exposure remains at a safe level, minimizing the risk of stochastic effects like cancer.

While the other provided options suggest higher limits, they exceed the established standards aimed at safeguarding occupational health, reflecting a lack of alignment with contemporary radiation protection protocols. Thus, 50 mSv is recognized as the appropriate and accepted annual dose limit for individuals working in environments with ionizing radiation exposure.
