What does ALARA stand for?

• A. As Low As Reasonably Achievable.
• B. All Levels Are Radiologically Acceptable.
• C. Avoidance Level and Radiation Action.
• D. Always Limit Any Radiation Activity.

Answer: (A)

ALARA stands for As Low As Reasonably Achievable. This safety approach focuses on keeping radiation exposure as small as possible, not by chasing an absolute limit, but by continually seeking practical ways to reduce dose while still accomplishing the required work. It means evaluating what can be done within realistic limits—using shielding, minimizing time near sources, maximizing distance, and employing remote handling or other controls—while considering cost, technology, and social factors. The idea is to optimize safety measures rather than declare a level acceptable without improvement. The other options don’t reflect the standard terminology or the practice of balancing feasibility and safety.
