Which statement completes the ALARA acronym accurately?

Which statement completes the ALARA acronym accurately?

• A. As Low As Readily Achievable
• B. As Low As Reasonably Accessible
• C. As Low As Reasonably Attainable
• D. As Low As Reasonably Achievable

Answer: (B)

Understanding how ALARA is expressed helps you apply the rule in practice. ALARA means keeping radiation exposure as low as reasonably achievable, which is about actively reducing dose while balancing practicality, cost, and effort. The statement that matches this standard wording is the one that says As Low As Reasonably Achievable. The other phrasings use terms like readily, accessible, or attainable, which do not reflect the established terminology and the regulatory emphasis on balancing dose reduction with feasibility. In real work, you’d apply shielding, distance, and time controls, along with administrative practices, to minimize dose to the extent practical without incurring disproportionate costs or impractical hindrances.
