What is the maximum deep dose equivalent for whole body exposure in mrem?

The maximum deep dose equivalent for whole-body exposure is established to ensure the safety and protection of individuals who may be exposed to radiation, especially in occupational settings. The limit is set to prevent adverse health effects, particularly concerning cancer risk resulting from radiation exposure. The regulatory guidance, particularly from organizations like the National Council on Radiation Protection and Measurements (NCRP) and the Environmental Protection Agency (EPA), specifies a limit of 5,000 millirems (mrem) for whole-body exposures in a year for radiation workers. This threshold is designed to provide a safety margin, reflecting a balance between the benefits and risks of exposure to radiation in controlled environments. Hence, this makes 5,000 mrem the correct answer, as it aligns with the established standards for acceptable radiation exposure limits in occupational settings.
