ALARA stands for which phrase in radiation protection?

• A. Approximate Level At Radiation Acceptable
• B. Always Limit And Reduce All
• C. As Low As Reasonably Possible
• D. As Low As Reasonably Achievable

Answer: (C)

The main idea is to keep radiation exposure as low as reasonably achievable, balancing safety with practical limits. The standard phrase is “As Low As Reasonably Achievable,” which emphasizes that dose should be minimized within what is realistically doable given current technology and circumstances. This wording reflects practicality and ongoing effort to reduce exposure as much as possible. Some sources or informal use may say “As Low As Reasonably Possible,” but the accepted, formal term uses achievable. The other options don’t fit because they either don’t reflect the established terminology or introduce wording that changes the meaning.
