x-ray production

Question 1

where do the most interactions occur?

Answer 1

between current electros and the outer shell electrons of tungsten

Question 2

what is characteristic radiation

Answer 2

the ionization of tungsten, causing fluorescence to release characteristic radiation

Question 3

Answer 3

0-10%

Question 4

what is the k-shell binding anergy of tungsten

Answer 4

69.5 keV

Question 5

how is characteristic radiation named

Answer 5

by the shell that is being FILLED

Question 6

discrete, line, homogenous, mono energetic, all describe what

Answer 6

characteristic radiation

Question 7

at what kVp values is up to 10% of the beam made up of characteristic radiation

Answer 7

70-150 kVp

Question 8

what is Bremsstrahlung radiation

Answer 8

when the very negative electrons are attracted to the nucleus, and change direction and deccelerate

Question 9

heterogenous, continuous, polyenergetic all describe what

Answer 9

Bremsstrahlung radiation

Question 10

what is intensity

Answer 10

the energy over a specific area over a period of time

Question 11

what is intensity affected by

Answer 11

the quality and quantity of the beam

Question 12
