RAD Quiz 3

Which of the following removes the soft x-rays for the x-ray beam as it exits the port?

• Collimator

• Filter

Which of the following best describes how x-rays are actually produced in the dental x-ray tube?

• High-speed electrons collide with target material electrons.

• Low milliamperage current is transformed to high kilovoltage current.

The intensity of the x-ray beam is affected by each of the following except one. Which one is the exception?

• Kilovoltage

• Target size

The filament and target are made out of tungsten because tungsten

• prevents electrons from being liberated.

• withstands high temperatures.

The duration of an x-ray exposure is determined by which control?

• Line switch

• Timer

The anode is composed of the focusing cup and the filament, and must be charged negative during x-ray production.

• Both parts of the statement are correct.

• Both parts of the statement are not correct.

Increasing which of the following would best increase the number of electrons flowing through the dental x-ray electrical circuit?

• Kilovoltage

• Milliamperage

How many electrical circuits are used in a dental x-ray machine?

• One

• Two

How does the radiographer know when the x-ray exposure cycle is complete?

• When the timer dial completes the rotation

• When the audible beep stops

Each of the following conditions must exist for x-rays to be produced except one. Which one is the exception?

• An air-filled glass tube

• High voltage to impart speed to the electrons
