What are the three definitions of x-radiation based on beam origin and interaction?

X-ray radiation is categorized by where the beam comes from and what happens to it as it travels. The primary radiation is the useful beam produced at the focal spot in the x-ray tube head. When this beam meets matter, it can generate additional photons; that produced radiation is secondary radiation. Some of these interactions deflect photons away from the original direction, creating scatter radiation. This three-part view—primary from the tube, secondary from interactions with matter, and scatter as deflected photons—fits the definitions based on beam origin and interaction. The other options describe specific production mechanisms or sources within the tubehead, but they don’t capture this origin-and-interaction framework.
