Which statement about ALARA practices is true?

Which statement about ALARA practices is true?

• A. Shielding is optional if the clinician is careful.
• B. Proper technique alone ensures ALARA.
• C. Shielding, proper technique, and considering alternative imaging all support ALARA.
• D. Always using the highest kVp to minimize dose.

Answer: (C)

ALARA is achieved by using a combination of dose-reduction strategies: shielding, proper technique, and considering alternative imaging when appropriate. Shielding helps block stray radiation and protect both patient and staff, especially when parts of the body outside the region of interest could receive scatter. Proper technique means choosing appropriate exposure factors, using precise collimation, and minimizing repeats, all of which directly influence the amount of radiation needed to obtain a diagnostic image. Considering alternative imaging methods, such as ultrasound or MRI, can eliminate radiation exposure entirely if they can answer the clinical question. That’s why the statement that best supports ALARA includes shielding, proper technique, and considering alternatives. Shielding isn’t optional, and technique alone doesn’t address all dose-reduction avenues. Using the highest kVp to minimize dose isn’t a blanket rule either; it can compromise image quality and may not reduce overall dose in every situation.
