Which term describes radiation produced when the primary beam interacts with matter?

• A. Scatter Radiation
• B. Secondary Radiation
• C. X-radiation
• D. Sensor

Answer: (B)

When the primary X-ray beam interacts with matter, new photons can be produced and existing photons can be deflected. The radiation that results from those interactions is called secondary radiation. This is a broad term that includes scattered photons (which deflect from their path) as well as characteristic X-rays emitted from the atoms in the material. Scatter radiation is a type of secondary radiation, but the term secondary radiation covers all radiation produced by the interaction, not just the scattered portion. X-radiation is a general label for X-ray photons and isn’t specifically defined by interactions with matter, and a sensor is not radiation.
