- Discuss which of the following factors you consider is more important for radiation: quality, quantity, primary versus remnant (exit), thickness of body part or type of tissue (atomic number). Justify your answer. Explain in your post how the x-ray is produced. As you describe the process, be sure to identify what is the source of free electrons, and define the concepts of electron acceleration, focusing of electrons, electron deceleration, target interactions, and Bremsstrahlung radiation in terms of their relation to the process. Also, describe the photon interaction with matter in relation to the Compton effect, photoelectric absorption, coherent (classical) scatter, and attenuation by various tissues.
