Which term best describes the practice to maintain exposures at the lowest level reasonably achievable in practice?

• A. As Low As Reasonably Achievable
• B. Always Low After Risk Assessment
• C. Avoidably Lowered Alarly
• D. All Levels Are Regulated Aggressively

Answer: (A)

ALARA stands for keeping exposure as low as reasonably achievable. The idea is to protect people by applying every practical measure to reduce risk, but without overdoing it beyond what is fair to spend of time, money, and effort. In practice, you implement protective layers: engineering controls and good procedures first, administrative controls second, and PPE as a last resort. Because zero exposure is often unattainable, the focus is on continuous improvement—reducing exposure further only if the extra effort or cost is justified by the amount of risk reduction gained. After a risk assessment, you select feasible controls and evaluate whether additional reductions are worth the resources required. This principle is what the tested term embodies, whereas the other phrasing options don’t reflect this balanced approach.
