RAD 100 ch 6 quiz review

The positive side of the x-ray tube is called

• Anode

• Cathode

• Focusing Cup

• Filament

The negative side of the x-ray tube is called:

• Anode

• Cathode

• Target

• Rotor

This is the process of "boiling off" of electrons:

• Compton scatter

• Pair production

• Thermionic emission

• Photoelectric effect

The x-ray tube focusing cup has a positive charge

• True

• False

The effective focal spot is different from the actual focal spot

• True

• False

This principle is a result of the electron stream striking an angled target at the Anode:

• Thermionic emission

• Anode heel effect

• Line focus

• Bremsstrahlung

Tungsten and Rhenium are used for the x-ray filament because:

• are inexpensive

• vaproize easily

• have a hight melting point

• add energy to the x-ray beam

The German word for braking is

• Draversthlung

• Bremsstrahlung

• Charastmic

• Leakage

When the electrons are stopped suddenly at the anode the production of ____ occurs:

• infrared radiation

• Magnetism

• Ultraviolet rays

• X-rays

X-rays have unique properties and include all of the following EXCEPT:

• Cause certain materials to light up

• Penetrate materials that absorb and reflect light

• Are harmless causing no biological effects

• Produce an image on photosensitive film
