What does ALARA stand for?

• A. As Low As Reasonable Achieveable
• B. As Low As Reasonably Achievable
• C. Always Limit As Radiation Amount
• D. As Low As Radiological Allowance

Answer: (B)

ALARA stands for As Low As Reasonably Achievable. It’s the guiding principle in diagnostic imaging to minimize radiation dose to patients and staff while still obtaining the necessary diagnostic information. In practice, this means optimizing exposure settings, using shielding and collimation, employing dose-saving technologies, choosing alternatives when feasible, and avoiding unnecessary repeats. The word “reasonably” reflects a balance: pushing doses down as low as possible without compromising image quality or diagnostic value. Other phrasings don’t capture this balance or use the correct wording.
