Radiation Physics

The lower the wavelength, the higher the energy of an electromagnetic wave

• True

• False

Ionization is the process of removing protons from an atom due to the interaction with an electromagnetic wave

• True

• False

This type of particle is a high speed electron released from a nucleus that turns a proton into a neutron

•  $\alpha\ -\ particle$  

•  $\beta^-particle$  

•  $\beta^+particle$  

• Characteristic X-Ray
  

Gamma radiation always occurs along side alpha or beta emission

• True

• False

In this interaction a photon hits an outer shell electron, it removes it and the photon changes its direction and loses energy

• Compton scattering

• Photoelectric effect

• Pair production

• Coherent scattering

A high energy photon is absorbed by a high atomic number atom and an inner shell electron is ejected. Immediately that void is filled by another electron from a higher energy shell

• Compton effect

• Photoelectric effect

• Coherent scattering

• Pair production

This physicist received the Nobel Prize for the discovery of the photoelectric effect

• Wilhelm Roengten

• Godfrey Houndsfield

• Albert Einstein

• Peter Mansfield

Characteristic X-rays are produced due to the Compton scattering effect

• True

• False

Becquerels (Bq) are the most basic unit to measure radiation exposure

• True

• False

The number of nuclear disintegrations per kilogram of radioactive material is a measure of?

• Exposure

• Absorbed dose

• Effective dose

• Equivalent dose
