What does ALARA stand for in radiology safety?

• A. As Low As Radiographers Accept
• B. As Low As Reasonably Achievable
• C. Always Limit Radiation Access
• D. Assigned Levels Avoid Radiation

Answer: (B)

ALARA means keeping radiation exposure as low as reasonably achievable. This guiding idea acknowledges that some exposure is unavoidable, but every radiology practice should minimize it as much as possible without compromising the diagnostic quality or clinical benefit.

In practice, that means using the lowest acceptable technique factors, limiting the exposed field with proper collimation, maximizing distance when possible, employing shielding, using dose-saving techniques in fluoroscopy (like pulsed modes and last-image hold), and avoiding repeats. It also relies on justification—each exam should be warranted and optimized to get the needed information with the smallest risk.

The other phrasing options don’t capture that balance of reducing dose while still achieving diagnostic goals, which is why the statement about ALARA is the best choice.
