Which term refers to the maximum permissible dose?

• A. Genetically Significant Dose
• B. As Low As Reasonably Achievable
• C. Mean Marrow Dose
• D. Maximum Permissible Dose

Answer: (D)

The idea being tested is the idea of a dose limit—the maximum exposure considered acceptable. The term that matches this concept is Maximum Permissible Dose, used to describe the highest amount of ionizing radiation a person should receive in a given period (often tied to occupational exposure limits). It’s a cap, not a target to minimize exposure, and it’s distinct from the other terms. Genetically Significant Dose refers to an estimate of the genetic impact on a population from gonadal exposure, not a per-person exposure limit. Mean Marrow Dose is the dose delivered to bone marrow, important for assessing hematologic risk, but it’s a tissue-specific dose measure, not a general permissible limit. As Low As Reasonably Achievable is a principle guiding how to reduce exposure, not a stated maximum.
