3. X-Ray Imaging

________ in which a photon is not absorbed but rather scattered.

________ are absorbed by a nucleus.

________ can occur when the energy of the incident photon exceeds 1.02 MeV.

________ bounces off in a new direction with little energy change.

A(n) ________ (positive electron, a form of anti- matter) is emitted with an electron.

________ is typically in the range of 100 nm to about 0.01 nm, or from 12 eV to 125.

6 ________ is enough to kick out an electron, and is the threshold of ionizing.

All ________ transfers to electron.

________ is used mostly with low energy diagnostic x- rays (mammography, thyroid scans)

________ of characteristic x- ray emission also decreases with increasing photon energy.

________ of an incident photon with a nucleus, which produces one (or more) ejected nuclear particle.

________ has lower atomic number so its not super frequent.

If the ________ is greater than the binding energy of the electron, then the photons.

________ in which a photon is absorbed, characteristic radiation is emitted along with photoelectrons, and possibly Auger electrons.

________ are called photons.

________ in which a photon is absorbed by the nucleus, a positron is emitted, and an electron is ejected.

________ is an electron volt, a unit of energy representing the amount of energy one electron can obtain from accelerating between the potential difference of 1 volt.

________ interacts with an electron (usually valence) and only some energy from the ________ goes to the electron.

The ________ is reduced, and an electron is ejected.

________ makes up most of the background noise & tissue damage.
