What is the maximum exposure limit for a member of the general public over one year?

The maximum exposure limit for a member of the general public is set at 100 mrem (0.1 rem) over the course of one year. This guideline is established by regulatory agencies to ensure that individuals who are not occupationally exposed to radiation (such as medical workers) are protected from excessive radiation doses.

This limit reflects a balance between allowing some level of exposure—thus recognizing that low doses of radiation are present in the environment and that incidental exposure is unavoidable—and safeguarding health. Maintaining a limit of 100 mrem helps mitigate the risk of potential health effects, particularly for sensitive populations and vulnerable groups.

The other exposure values listed in the choices are primarily designed for other groups or specific scenarios rather than for the general public, which is why they are not applicable in this context.
