ALARA Principle

Definition

The ALARA principle stands for 'As Low As Reasonably Achievable' and is a safety concept aimed at minimizing radiation exposure to patients and medical staff during medical imaging procedures. This principle emphasizes the importance of keeping radiation doses as low as possible while still achieving the necessary diagnostic quality of images. By integrating this principle into medical imaging practices, healthcare providers can enhance patient safety and reduce potential risks associated with radiation exposure.
