ALARA stands for?

ALARA stands for?

• A. As low as reasonably achievable
• B. As high as reasonably achievable
• C. Always low and accurate
• D. As long as radiation is allowed

Answer: (A)

ALARA is about keeping radiation exposure as low as reasonably achievable. It means the protection team should continuously optimize and reduce dose by using practical measures—like shielding, distance, and minimizing time—while also considering what’s feasible given technology, costs, and benefits. The idea isn’t to chase zero, but to balance risk reduction with real-world constraints. The correct phrasing—“As Low As Reasonably Achievable”—captures that balance. The other options don’t fit the concept: “as high as reasonably achievable” would aim for more exposure, which goes against safety goals; “always low and accurate” isn’t a recognized policy and isn’t a workable standard; “as long as radiation is allowed” misses the proactive effort to minimize exposure.
