_____ 1. X-ray photon passed through atom unchanged; no interaction _____ 2. Coherent scatter _____ 3. Photoelectric effect _____ 4. Compton scatter _____ 5. Bremsstrahlung radiation _____ 6. Radioactivity A. Electrons stop suddenly as they hit the anode. B. Ionization takes place when the photon ejects an outer shell electron. This results in the loss of energy for the photon and a negative charged electron. The low energy photon changes direction. C. An unstable atom releases energy...

X-rays: Typical diagnostic wavelength and photon energy range. - Answer-100ev-200 keV min. wavelength 6pm-12nm Structure and function of the x-ray tube. - Answer-A vacuum tube with an anode and a cathode. The cathode is heated and electrons are emitted, they are accelerated by a voltage difference in the tube. When the "brake" against the material of the anode, they release their high kinetic energy in the form of an x-ray. *x-ray tubes are of very low efficiency, most of the radiation i...
