100 What is Classical Interaction, Thomson Scattering What two names is Coherent Scattering also referred as?	100 What is yes Does this interaction ionize an atom?	100 What is inner-shell electron What does the incident photon interact with?	100 What is Nucleus What does the incident electron interact with?	100 What is the Nucleus What does the incident electron interact with?
200 What is Low Energy Less than 10 KeV What is the energy level of the incident x-ray photon	200 What is Fog What is created when a Compton Scatter electron hits the image receptor?	200 What is yes Does the Photoelectric Effect contribute to patient dose?	200 What is at least 1.02 MeV What energy does pair production occur?	200 What is High Energy 10 MeV What energy does Photodisintegration occur?
300 What is B. Slightly affect patient dose Does Coherent Scattering: A. Not affect patient dose B. Slightly affect patient dose C. Greatly affect patient dose	300 What is 2/3rds How much energy do Compton Scatter Photons retain?	300 What is Compton Scattering Photoelectric Effect and what other interaction contribute to image production?	300 What is Nuclear Medicine What modality of imaging does Pair Production occur?	300 What is by ejecting a nuclear particle How does the atom become stable again?
400 What is Orbital Electron What does the incident x-ray photon interact with?	400 What is Secondary Photons What is created after the Characteristic Cascade?	400 What is more Soft tissue has a lower binding energy Does a photoelectron that interacts with soft tissue have more or less left-over kinetic energy?	400 What is Positron & Electron What two particles are created during this interaction	400 What is when the x-ray photon is absorbed by matter When does absorption occur?
500 What is no Does this interaction ionize the atom?	500 What is middle or outer shell electron What does the incident photon interact with?	500 What is Absorption What is necessary to create an x-ray image?	500 What is Annihilation Name the process where the positron travels until it strikes an electron and is converted to energy	500 What is reduction in energy/ # photons in the primary beam as it passes through matter What is Attenuation?
