The MPD is the radiation doses recommended for which groups?

• A. pediatric patients only
• B. the general population, occupational worker and pregnant person
• C. general population only
• D. occupational workers only

Answer: (B)

Maximum Permissible Dose is the set of recommended upper exposure limits designed to protect people who are more sensitive or more exposed to radiation. These limits apply to three groups: the general public, workers who may be exposed occupationally, and the fetus of a pregnant person. In dental radiography, recognizing these categories helps ensure that everyone’s exposure stays within safe bounds, with special consideration given to the developing fetus during pregnancy. The correct choice reflects that MPD covers all three groups, not just one or two, which is why it’s the best answer.
