What is the maximum permissible dose for radiation workers?

The maximum permissible dose for radiation workers is set at 50 millisieverts (mSv) per year. This limit is established to ensure that the health and safety of individuals who work with or around radiation sources are adequately protected. Regular exposure to radiation can lead to adverse health effects, including an increased risk of cancer, so the regulatory framework in place seeks to minimize this risk while allowing for necessary occupational exposure.

This limit of 50 mSv is based on reviews of data regarding radiation exposure and its associated risks. Regulatory guidance, such as that provided by organizations like the International Commission on Radiological Protection (ICRP), takes into account both the potential health risks and the practical needs of radiation workers in various fields, ensuring that while they can perform their jobs effectively, their exposure remains within safe levels.

The other options represent limits that exceed the established safety standards for radiation workers, which would not be considered acceptable for regular occupational exposure.
