ALARA stands for as low as reasonably ___.

ALARA stands for as low as reasonably ___.

• A. Acceptable
• B. Allotted
• C. Achievable
• D. Allowable

Answer: (C)

In radiological protection, the goal is to minimize exposure as much as feasible, balancing safety with practicality. The missing word is achievable because ALARA means we should keep doses as low as possible within the limits of current technology, economic considerations, and social factors. The qualifier “reasonably” acknowledges that there’s a point where further reduction isn’t worth the effort, cost, or disruption, so we evaluate which dose-reduction measures are practical and beneficial. The other terms don’t fit this idea: acceptable or allowable would imply a fixed threshold or permission to stay within a limit, while allotted isn’t about optimization. ALARA focuses on actively reducing exposure beyond mere compliance, whenever it is reasonably feasible.
