What does ALARA stand for?

• A. As Light As Readily Acceptable
• B. As Low As Reasonably Achievable
• C. Always Limit And Reduce Amounts
• D. As Low As Realizable And Returnable

Answer: (B)

ALARA stands for As Low As Reasonably Achievable. The idea is to minimize exposure to the hazard as far as reasonably possible, balancing the level of protection with practical considerations like technology, cost, and logistics. In practice you use a layered approach—limit time near the source, maximize distance, apply shielding, and implement safe work practices—to push exposure down as far as is feasible without imposing undue burden. It’s important to note that zero exposure isn’t required or expected; further reductions must be reasonable in cost and effort. The other phrasings aren’t the standard term and don’t reflect this balanced, practical approach.
