1
New cards

photon passes through pts atom, hits nothing, atoms unchanged

No interaction

2
New cards

Photons hit receptor + energize silver halide crystals

No interaction

3
New cards

Best interaction

No interaction

4
New cards

NO ionization or scatter radiation

No interaction

5
New cards

Photon hits no e- misses nucleus

No interaction

6
New cards

Total transfer of energy from x-ray photon to atoms of matter the x-ray beam produces

Absorption

7
New cards

Photon dislodges inner orbit e-

Absorption/photoelectric effect

8
New cards

Ionization occurs; photon hits inner e- and gives up all energy to eject it

Photoelectric effect

9
New cards

Loses ALL energy b/c it’s working to eject an inner orbit e-

Absorption/photoelectric effect

10
New cards

In the photoelectric effect, what happens to the ejected e-

It is absorbed by other atoms

11
New cards

photon completely absorbed by atom it hit; no further radiation

Absorption of energy and photoelectric effect (Non scattering)

12
New cards

Doesn’t travel any further to interact w/ more atoms

Absorption of energy and photoelectric effect (Non scattering)

13
New cards

Accounts for 30% of interactions

Absorption of energy and photoelectric effect (Non scattering)

14
New cards

Photon hits outer shell e- and gives up some energy to eject it

Compton scatter

15
New cards

62% of interactions

Compton scatter

16
New cards

Photon is slower and bounces off another direction and may interact w/another atom

Compton scatter (scattering)

17
New cards

Ejected e-

Compton e-

18
New cards

Photon’s path changes and slows down, continues on

Compton scatter

19
New cards

X-ray photon that has its path altered while passing through an outer shell e- orbit

Coherent scatter

20
New cards

No e- ejected/photon doesn’t hit e-

Coherent scatter

21
New cards

Orbit changes photons path as it travels next to atom

Coherent scatter (scattering)

22
New cards

No energy loss, just a detour

Coherent scatter (scattering)

23
New cards

8% of interactions

Coherent scatter
