As photon energy increases beyond the binding energy of the K electron, the ____ effect decreases rapidly and the _____ effect becomes more important.

Neutrons are indirectly ionizing.

The fluence rate of a photon beam is the fluence per unit time.

The probability of this interaction occurring is Z3/E3.

The energy of the incident photon must be equal to or slightly greater than the electron-binding energy in a Compton interaction.

What is the mass attenuation coefficient for the problem above (#33)? Copper has a density of 8.9 g/cm3.

Select all particles that exhibit a Bragg peak.

If we consider a photon beam traversing through a material, the fraction of photon energy transferred into KE of charged particles per unit thickness of absorber is given by:

Charged particles interact primarily by:

Select all that are considered directly ionizing radiation.
