What does ALARA stand for in dental radiography, and what does it mean for practice?

• A. As Low As Reasonably Achievable
• B. All Levels Are Readily Achievable
• C. As Low As Reasonably Accessible
• D. Always Limit Amounts Radiographically Adequate

Answer: (A)

ALARA stands for “As Low As Reasonably Achievable.” In dental radiography this means we minimize radiation exposure to patients and staff to the smallest level that still provides a diagnostically useful image. Practically, that means justifying every radiograph, optimizing exposure factors to the patient’s size and diagnostic need, using the fastest imaging technology available, and restricting the beam with proper collimation. It also involves shielding, careful technique to avoid retakes, and considering alternatives when appropriate, all while maintaining equipment and following protocols so the total dose remains as low as reasonably achievable within practical limits.
