Which of the following types of radiation exposure is NOT considered in the occupational dose limit for workers?

Medical exposure is not considered in the occupational dose limit for workers because the regulations governing occupational exposure specifically define the limits in regard to the type of exposure that an individual receives as part of their job responsibilities. Occupational exposure refers to the radiation dose received by workers while performing their duties, and it is closely regulated to protect their health and safety.

Medical exposure, on the other hand, primarily includes the radiation dose received by patients for diagnostic or therapeutic purposes and is subject to different guidelines and considerations. These exposures are intended for the benefit of the patient, not the healthcare worker, hence they are exempt from the occupational dose limits set for workers.

Occupational, public, and environmental exposures all relate to the potential radiation dose to individuals in their respective contexts, either through their work, as members of the public, or due to environmental factors, all of which are considered in dose limits.
