Radiation Physics-Unit 10 review

Front

What is the speed of light in meters per second?

Back

3 x 10^8 meters/second.

Front

What causes the conversion of the incident electron's kinetic energy to heat?

Back

Heat results from excitation.

Front

What is the resulting x-ray energy if the incident electron makes a small/medium turn near the nucleus in brems production?

Back

The resulting x-ray energy will be low/medium.

Front

What effect does filtration have on the average energy of the beam?

Back

Filtration increases the average energy of the beam.

Front

What does kVp represent in terms of the beam?

Back

kVp represents the quality of the beam.

Front

Define bremsstrahlung radiation.

Back

Bremsstrahlung radiation is produced when an electron is decelerated or deflected by the electric field of a nucleus.

Front

What is the relationship between kinetic energy and x-ray production?

Back

Higher kinetic energy of incident electrons can lead to higher energy x-rays produced.

Front

Explain the term 'excitation' in the context of radiation physics.

Back

Excitation refers to the process where an electron absorbs energy and moves to a higher energy state.

Front

What is the role of filtration in radiation physics?

Back

Filtration removes low-energy photons from the beam, increasing the average energy and quality of the beam.

Front

How does the energy of x-rays relate to the potential difference (kVp) applied?

Back

Higher kVp results in higher energy x-rays due to increased kinetic energy of the electrons.
