What does ALARA stand for?

• A. Always Low And Regularly Assessed
• B. As Low As Reasonably Achievable
• C. As Least As Regrettably Achievable
• D. Always Limit And Reduce Applications

Answer: (B)

ALARA is the approach that radiation exposure should be kept as low as practically achievable, balancing the benefit of the imaging or procedure against the risk of harm. The correct phrasing is “As Low As Reasonably Achievable.” This means we continuously seek to minimize dose by using the lowest acceptable imaging parameters, adequate shielding, shorter exposure times, and greater distance from the source, while maintaining the necessary diagnostic quality. The “reasonably achievable” part means practical factors like cost, feasibility, and patient-specific considerations are taken into account—we don’t demand zero dose, but we do strive to reduce it as much as is practical. For example, choosing appropriate exposure settings, using protective barriers, and avoiding unnecessary repeats are all ALARA practices. The other options don’t reflect the recognized term or the protective philosophy they imply, so they’re not correct.
