Rad protection Interactions Quiz Flashcards
When low-energy photons (which may be thought of as moving waves) interacts with an atom it may transfer its energy by causing some or all of the electrons of the Atoms to vibrate momentarily
Process of coherent scattering
Incoherent, inelastic, or modified scattering
Compton scattering
What is Compton scatter responsible for?
Most of the scattered radiation produced during radiographic procedures
Where can Compton scattering be directed?
Directed forward as small angle scatter, backward as back scatter, and to the side for side scatter
Incoming x-ray photon interacts with loosely bound electrons of an atom of the irradiated objects on encountering the electron the incoming x-ray photons surrenders a portion of its kinetic energy to dislodge the electron from its outer shell orbit thereby ionizing the biologic Atom
Process of Compton scattering
Photo electric absorption is the most important interaction between?
X-ray photons and atoms of the patient’s body for producing useful images
Photoelectric absorption KvP range is
23-150 kVp
Photoelectric absorption is an interaction between?
X-ray photons and an inner shell electron
What is the probability of photoelectric absorption depend on?
Amount of energy lost is equal to the difference in the binding energies is associated with each electron shell
What does pair production strongly interact with?
The nucleus of an atom of the irradiated biologic tissue
In pair production what does the energy of the photon transform into?
Two particles. A negatron and a positron
What is photodisintegration?
And interaction that occurs about 10 and MeV and high-energy radiation therapy
Classic, elastic, or Unmodified scattering?
Coherent scattering
