1
Q
an incident x-ray is absorbed and has enough energy to knock out and inner orbit electron resulting in the emission of a photon
A
coherent scatter
2
Q
an incident x-ray is absorbed and not scattered?
A
photoelectric absorption
3
Q
in photoelectric absorption, the one that was ejected
A
photoelectron
4
Q
in photoelectric absorption, the secondary photon given off when the electron jumped down
A
characteristic radiation
5
Q
in photoelectric absorption, missing an outer shell electron
A
positive ion
6
Q
an incident x-ray is scattered like a cue ball hitting a pool ball
A
Compton scatter
7
Q
every cm of thickess cuts the amount of radiation by half
A
mono energetic attenuation
8
Q
increasing cm of thickness cuts the amount of radiation by half
A
polyenergetic attenuation
