ALARA stands for?

• A. As Low As Reasonably Achievable
• B. As Low As Remote Achievable
• C. As Light As Reasonably Achievable
• D. Always Low And Reasonably Achievable

Answer: (A)

The main idea is to keep radiation doses as low as practically possible. This means using every reasonable safety measure to reduce exposure, while recognizing that some exposure is inevitable and must be balanced with practicality and resources. The standard phrase captures this: As Low As Reasonably Achievable. In practice, this principle drives you to optimize shielding, maximize distance from sources, and minimize time spent near sources, along with engineering controls, administrative procedures, and continuous monitoring. The goal isn’t zero exposure, but the lowest dose that can be achieved given costs, technology, and feasibility. Why the other phrasings don’t fit: they incorrectly state or imply aspects not part of the standard concept (for example, suggesting “remote,” “light,” or always achieving a low dose without effort). The recognized phrase emphasizes balancing dose reduction with real-world constraints while pursuing ongoing improvement.
