What is the maximum permissible dose of radiation for radiation workers according to NRC regulations?

The maximum permissible dose of radiation for radiation workers, as established by the Nuclear Regulatory Commission (NRC) regulations, is set at 50 mSv (5 rem) per year. This limit is designed to ensure the safety and health of individuals who work with or around radioactive materials, taking into consideration both the risks associated with radiation exposure and the need to balance this with the operational requirements of their jobs.

The 50 mSv limit is a guideline that is considered protective of health when applied to a working population over the course of their employment. Regular monitoring and measures are put in place to keep radiation exposure as low as reasonably achievable (ALARA), which helps maintain worker safety and minimizes the risk of long-term health effects like cancer. This regulatory framework is crucial in promoting a culture of safety in environments where radiation exposure is a potential hazard.

Other options, while being lower limits, do not align with the NRC's standards for radiation workers and do not reflect the established regulatory threshold for occupational exposure.
