ALARA is an acronym for:

• A. As long as reasonably achievable
• B. As little as reasonably achievable
• C. As long as radiologist allows
• D. A radiation protection concept that encourages radiation users to keep the dose to the patient as low as reasonably achievable

Answer: (D)

ALARA means aiming to keep radiation exposure as low as reasonably achievable. The correct statement captures this protective mindset: it describes ALARA as a principle that urges radiation users to minimize the dose to the patient while still obtaining the necessary diagnostic information or treatment outcome, balancing practicality, safety, and usefulness. This isnues the idea that you don’t always push doses to the absolute minimum or set one fixed limit; instead you optimize, using the least dose that still achieves the clinical goal, with sensible measures like proper shielding, appropriate exposure settings, collimation, and avoiding unnecessary repeats. The other options miss this balance or misstate the concept—for example, suggesting a longer duration, or treating dose as something only controlled by one person, or implying “as little” rather than “as low as reasonably achievable.”
