Primary radiation exits the tube.

• True
• False

Photons may be absorbed.

• True
• False

Image detail is affected by photographic properties and geometric properties.

• True
• False

contrast and density

• Photographic Density
• radiographic density
• high Density
• low density

One kilovolt =

• 1000 volts
• 2000 volts
• 3000 volts
• 10000 volts

One milliampere (mA) =

• one thousandth of an ampere.
• two thousandth of an ampere.
• seven thousandth of an ampere.
• ten thousandth of an ampere.

Technologists think in terms of mAs.

• True
• False

primary function of mAs

• density

• mAs
• kVp

controls how many electrons are coming at the target

• mA
• mAs
• kVp
• density

a combination of how many and for how long

• mAs
• kVp
• density
