ALARA stands for

ALARA stands for

• A. Always Limit And Reduce Activity
• B. All Levels Are Readable
• C. As Low As Required And Achievable
• D. As Low As Reasonably Achievable

Answer: (D)

ALARA stands for keeping radiation exposure as low as reasonably achievable. This principle guides radiographers to minimize dose to patients, staff, and themselves while still obtaining the needed diagnostic information. In practice, it means using the shortest exposure time possible, maximizing distance from the source, providing appropriate shielding, and carefully shaping the X-ray beam (collimation) to the area of interest. It also involves selecting the lowest acceptable exposure factors, ensuring proper technique, and avoiding repeat examinations through good planning and technique. The term "reasonably achievable" emphasizes a balance: dose reduction should be pursued, but not at the expense of practicality, safety, or timely patient care. Other phrases don’t capture this standard balancing approach and are not the correct representation of ALARA.
