Ch3-5 Radiation protection

the highest voltage established across the xray tube is known as

• kev

• kvp

• peak kvp

• mas

The glass window in the xray tube acts as

• added filtration

• inherent filtration

• external filtration

• internal filtration

Added filtration is made of

• copper

• aluminum

• nickel

• gold

combination of glass window and aluminum is called

• extrinsic filtation

• permanent inherent filtration

• permanent internal filtration

primary radiation is

• xrays that pass through glass window

• xrays that pass through both filtration

• xrays produced at the anode

IF 70 kvp is applied, the highest energy xray photon will be

• 70 kvp

• 70 kev

• 45 kev

• 45 kvp

average energy of a photon is usually

• 1/3 of the kvp

• 1/2 of kvp

• 1/3 of mas

• 1/2 of mas

Indirect transmission is always the result of

• high kvp

• scatter

• low kvp

exit photons that have a different direction than the primary photons are called

• radiographic fog

• small angle scatter

• noise

Photons that do not reach the IR are called

• primary photons

• exit photons

• attenuated photons
