  1. 5. is a parameter used in radiation physics to describe how a material attenuates or reduces the intensity of a beam of radiation as it passes through.
  2. 7. refers to the amount of radiation energy passing through a particular area in each amount of time. It's a measure of the rate at which radiant energy is emitted, transmitted, or received per unit area.
  3. 8. can occur when an incident photon has energy equal to or greater than the binding energy of electron in atom.
  4. 9. refers to the thickness of a material that reduces the intensity of a beam of radiation by half.
  5. 10. refers to the rapid decrease in the intensity of a beam of radiation as it passes through a material.

  1. 1. also known as Thomson, Rayleigh, Classical and Unmodified scattering
  2. 2. is a process that can occur when high-energy X-rays interact with matter. Produces two electron with mass of one equal to 0.51 MeV
  3. 3. is the reduction in x-ray intensity that results from absorption and scattering.
  4. 4. Electron is ejected from atom and photon is scattered with some reduction in energy
  5. 6. discovered classical scattering of x-ray with an electron.
