ALARA is primarily used in which medical context?

Explanation:
ALARA stands for As Low As Reasonably Achievable, and it is applied to minimize radiation exposure in medical imaging. Because imaging uses ionizing radiation, the goal is to obtain the needed diagnostic information with the smallest dose possible. This is achieved through shielding, proper beam collimation to limit the exposed area, maximizing distance when feasible, using the lowest dose settings that still provide acceptable image quality, and avoiding unnecessary repeats. Other areas like pharmacy or rehabilitation don’t routinely involve ionizing radiation, while imaging may occur during some surgical procedures, ALARA is most closely tied to imaging practices.
