What does ALARA stand for?

• A. All Levels Are Readily Acceptable
• B. As Low As Reasonably Achievable
• C. As Low As Radiation Allowed
• D. As Low As Radiation Are

Answer: (B)

ALARA means As Low As Reasonably Achievable. This principle guides how we handle ionizing radiation by aiming to minimize exposure to the lowest level that can be practically achieved, without causing undue cost, effort, or risk. It’s about ongoing optimization: use shielding and containment, maximize distance from the source, minimize time near the source, and apply procedural and engineering controls. In practice, this means things like proper room shielding, wearing protective gear as needed, using remote handling or automation when possible, and closely monitoring doses to ensure they stay as low as reasonably possible. The other phrasings aren’t standard or correct and don’t capture the intended balance between protection and practicality.
