ALARA stands for what?

• A. As Low As Reasonably Achievable
• B. As Long As Radiation Acceptable
• C. Always Limit And Reduce Activity
• D. Automatic Level And Real-time Adjustment

Answer: (A)

The main idea here is ALARA: keep exposure as Low As Reasonably Achievable. This principle means we aim to minimize the amount of exposure used to get a diagnostic-quality result, while still meeting the clinical objective, and we factor in what’s economically and socially reasonable. In practice, that means optimizing technique, using the lowest acceptable settings, proper shielding or collimation when appropriate, and justifying each exposure so it’s truly necessary. Even though ultrasound uses non-ionizing energy, the same mindset applies: use the lowest output and exposure that still yields a usable image to protect patients and staff. The other options don’t reflect this standard term—they’re not the recognized phrase for this safety principle.
