Which type of exposure is specifically related to those who are not classified as radiation workers?

The correct answer is public exposure because this term specifically refers to radiation exposure that affects individuals who are not classified as radiation workers. Public exposure encompasses the radiation doses received by the general population, which can occur from various sources, such as natural background radiation or medical procedures where individuals are not directly involved in the radiation work itself.

Public exposure is a critical consideration in radiation safety, as it is essential to protect non-workers from unnecessary radiation risks. This type of exposure is often regulated to ensure that individuals who are not involved in radiation-related professions are kept safe from excess radiation.

In contrast, occupational exposure pertains to doses received by individuals who work with radiation in a professional capacity, such as medical personnel. Medical exposure typically references doses received by patients during diagnostic or therapeutic procedures. Therapeutic exposure is related to radiation delivered to patients for treatment purposes, which also does not apply to the general population.

Thus, public exposure accurately captures the concept of exposure relevant to individuals outside the workforce defined as radiation workers.
