RT 111 Flashcards

1
Q

Explain Anode Heat

A
  1. projectile e interact w/ outer shell e
  2. low energy = NOT ionize, but excited
  3. excited outer shell e releases heat/infrared
  4. e returns to og state

Q

Explain Characteristic Radiation

A
  1. projectile e interact w/ inner shell
  2. inner shell ionize = e void
  3. outer shell e fill vacancy
  4. transition of outer to inner = charac x-rays

*low energy = orbital e fill is far from void
*high energy =orbital e fill is near void

Q

Explain Bremsstrahlung Radiation

A
  1. projectile e miss orbital e, interact w/ nuclear field
  2. projectile e is slowed down & change direction
  3. slowed down fx = brems

*low energy =pe barely influenced by nuclear field (deflection =far)
*high energy =pe highly influenced (deflection =close to nucleus)
