ALARA is about keeping radiation exposure as low as possible. The main idea is to minimize dose to patients and staff while still obtaining the necessary diagnostic information. In dental radiology, this means justifying every radiographic image, optimizing exposure settings, using shielding and proper collimation, selecting fast sensors or films, and avoiding repeat exposures. The correct phrase is As Low As Reasonably Achievable. The other phrases do not reflect standard safety terminology and would misstate how we think about radiation exposure.
