Ionization Any process by which a neutral atom gains or loses an electron.
Ability to disrupt composition of matter & is capable of disrupting life processes
Special protection to prevent excessive exposure to ionizing radiation
Radio waves Another form o
Target Interactions - filament electrons penetrate the face of the target
- to depth of approximately 0.5 mm
- interacting with the tungsten target atoms in their path
- produce x-rays in two ways: characteristic interactions and bremsstrahlung interactio
Classical interactions (Coherent scattering) also known as "Thomson scattering"
- incident x-ray photon interacts with an orbital electron of a tissue atom and changes direction
- low energy (less than 10 keV)
-not likely to ionize (remove orbital electro
Ionizing radiation - energy capable of penetrating matter
- possesses sufficient energy to eject orbital electrons along its path
- thus ionizing atoms
Radiation forms of energy emitted and transferred through matter
Two sources of ionizing radiation natu
Tube head assembly composed of the protective housing and x-ray tube
Protective housing - a lead-lined metal structure with two large electrical cables
- solid, stable mechanical support
- provides a thermal cushion for the tube
- absorbs most of the leak
