Ionizing radiation emitted from the x-ray tube housing in directions other than the useful beam is termed?

• A. Scattered radiation
• B. Leakage radiation
• C. Extra-focal radiation
• D. Recoil radiation

Answer: (B)

Leakage radiation is the portion of x-ray photons that escapes through the protective housing of the tube, traveling in directions other than the intended useful beam. Even with shielding and a properly designed port, some photons leak out of the housing as the tube operates. This stray radiation contributes to occupational exposure and is why protective barriers and staying a safe distance from the tube are important. It differs from scattered radiation, which originates when primary photons interact with matter (like the patient) and change direction, and from extra-focal radiation, which are additional photons produced when electrons strike parts of the tube outside the main focal spot.
