Stray radiation includes leakage and scatter; what term describes radiation not serving a purpose?

• A. Leakage radiation
• B. Scatter radiation
• C. Primary radiation
• D. Stray radiation

Answer: (D)

Stray radiation describes all radiation outside the useful imaging beam that doesn’t contribute to image formation. It includes leakage from the tube housing and scatter produced when X-rays interact with matter. Since both leakage and scatter are unwanted, non-productive radiation, the umbrella term stray radiation best describes radiation not serving a purpose, whereas primary radiation is the useful beam, and leakage and scatter are components of stray.
