X-ray interaction and production

Question 1

auger electron

Answer 1

incomming electron–> electron kicked out–> filled up by outer shell –> kicking out outer shell electron–> free auger electron

Question 2

excitation

Answer 2

loss of kinetic energy, electron introduced to higher energy levels

Question 3

ionization

Answer 3

loss of kinetic energy, electron will be kicked out

Question 4

Specific ionization

Answer 4

number of ion pairs produced per unit length of its path, higher the charge the higher number of ionpairs

Question 5

linear energy transfer

Answer 5

amount of energy deposited per unit path length, hoeveelheid straling die verloren gaat, hoe hoger hoe schadelijkerQ^2/Ek, high LET has high charge

Question 6

Elastic scattering

Answer 6

without energy loss

Question 7

inelastic energy loss

Answer 7

energy of scattered electron in lower, can cause ionization

Question 8

deflection

Answer 8

degree to which electron is displaced after scattering

Question 9

Brehmstrahlung

Answer 9

produced by heavy attraction of the nucleus–> deaccelerated in different direction (smaller the particle, higher proprability of bremssstrahlung), energy depends on distance from nucleus

Question 10

Gamma ray

Answer 10

nucleus of radionuclide gets attact –>decay (verval) produces gamma

Question 11

rayleigh scattering

Answer 11

not so important, inertaction with entire atom, emitted and scattered photon have same energy and wavelength

Question 12

compton scattering

Answer 12

interaction with outer shell electron, outgoing photon has larger wavelength because it loses energy (energy loss transfered to compton electron

Question 13

photoelectric effect

Answer 13

X-ray interacts with electron in inner shell –> energy of photon completely transferred to a free photoelectron–> characteristic x-ray of auger electrons
