Which of the following is NOT a type of interaction of X-rays with matter?

• A. Scattering
• B. Absorption
• C. Reflection
• D. Transmission

Answer: (C)

The correct answer, which identifies a type of interaction that is NOT associated with X-rays interacting with matter, is reflection. In the context of X-ray physics and radiation safety, the primary interactions that X-rays have with matter include scattering, absorption, and transmission. Scattering occurs when X-rays interact with matter and deviate from their original path; this can result in a partial loss of energy. Absorption refers to the process in which X-rays are completely absorbed by the matter they encounter, effectively transferring their energy to the material. Transmission describes the scenario where X-rays pass through an object without interacting with it, indicating that some amount of the radiation can penetrate the material without being significantly altered. While reflection is a common phenomenon with visible light, it is not a notable interaction that X-rays exhibit when they encounter materials. X-rays typically penetrate through matter rather than bouncing off surfaces. Thus, reflection does not play a significant role in the interactions of X-rays with matter, making it the correct response in this context.
