What is one of the main principles of ALARA?

The principle of ALARA, which stands for "As Low As Reasonably Achievable," emphasizes the importance of minimizing radiation exposure to both patients and staff while still achieving the necessary diagnostic results. Choosing to keep exposure levels as low as possible is fundamental to this principle because it seeks to balance the necessity of imaging procedures with the potential risks associated with radiation.

This principle is anchored in the belief that radiation should be used judiciously, and efforts should be made to achieve diagnostic goals while reducing unnecessary exposure. By adhering to ALARA, healthcare professionals can uphold safety standards and protect patient health, all while still providing effective diagnostic imaging.

Other options, like minimizing patient discomfort or performing exams under supervision, are important aspects of patient care and operational protocols in radiology, but they do not specifically address the core tenet of reducing radiation exposure, which is central to the ALARA principle. Similarly, using high doses for better imaging contradicts the very essence of ALARA, as it would lead to higher radiation exposure without necessarily improving diagnostic outcomes.
