Why is radiation dose kept as low as reasonably achievable (ALARA)?

Why is radiation dose kept as low as reasonably achievable (ALARA)?

• A. To minimize health risks associated with radiation exposure.
• B. To maximize energy production.
• C. To simplify regulatory compliance.
• D. To reduce maintenance costs.

Answer: (A)

ALARA is about protecting people from radiation by keeping exposure as low as reasonably achievable. The main idea is to minimize health risks from radiation, including long-term cancer risks from cumulative dose and potential acute effects at high doses, by applying practical steps such as limiting time near sources, increasing distance, and using shielding and safe work practices. The “reasonably achievable” part means we balance what’s feasible with costs and practicality, so we continuously seek better, safer ways to perform work without compromising essential goals. While energy production, regulatory compliance, and maintenance costs matter in a broader sense, ALARA focuses on reducing dose to protect health as the primary objective.
