RT 111 Flashcards by Queenie Francisco

Explain Anode Heat

projectile e interact w/ outer shell e
low energy = NOT ionize, but excited
excited outer shell e releases heat/infrared
e returns to og state

Explain Characteristic Radiation

projectile e interact w/ inner shell
inner shell ionize = e void
outer shell e fill vacancy
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

Explain Bremsstrahlung Radiation

projectile e miss orbital e, interact w/ nuclear field
projectile e is slowed down & change direction
slowed down fx = brems

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