Radiation Physics

The process by which radiation results in the formation of a negatively charged electron and a positively charged ion

• Binding Energy

• Braking Radiation

• Characteristic Radiation

• Ionization

When electrons from the cathode travel close to the nucleus of the tungsten atom, which will either decelerate this electron or stop it.

• Braking radiation

• Characteristic radiation

NGSS.HS-PS4-3

When the cathode electron collides with the inner shell electron and ejects it causes ionization of the atom.

• Braking radiation

• Characteristic radiation

When --- increases, the quality of the x-ray increases (you can choose more than one answer)

• exposure time

• tube current

• tube voltage

• target-patient distance

• filtration
