|---|---|---|---|---|---|
| Absorbed Dose | Amount of energy deposited in any form of matter, by any type of radiation.
🗑
|
||||
| Background Radiation | Ionizing radiation always present in the environment.
🗑
|
||||
| Characteristic Radiation | Produced when an electron from the tube filament connects with an orbiting electron.
🗑
|
||||
| Coherent Scattering | Low energy x-ray passes near an atoms outer electron, which results in a scatter but no loss of energy.
🗑
|
||||
| Compton Effect | Dental x-ray interacts with an orbital electron, and the x-ray energy is transferred to the electron.
🗑
|
||||
| Decay | Happens when an unstable isotope tries to regain stability by releasing energy.
🗑
|
||||
| Dose | When the radiation is absorbed into the tissues.
🗑
|
||||
| Dose Equivalent | Used for radiation protection to compare the biological effects to various radiation. Absorbed dose x biological effect.
🗑
|
||||
| Effective Dose Equivalent | Used to compare the risk of the radiation exposure producing a biological response.
🗑
|
||||
| Electromagnetic Radiation | Movement of wavelike energy through space as a combination of electric and magnetic fields.
🗑
|
||||
| Exposure | The measurement of ionization in air produced by x-rays.
🗑
|
||||
| Frequency | Measurement of waves that pass a given point per unit of time.
🗑
|
||||
| Gray | (Gy). Unit for measuring absorbed dose.
🗑
|
||||
| Hard Radiation | Radiation with great penetrating power.
🗑
|
||||
| Ionization | Is the formation of ion pairs.
🗑
|
||||
| Ionizing Radiation | Radiation that produces ions.
🗑
|
||||
| Photon | Bundles of energy that travel at the speed of light.
🗑
|
||||
| Rad | Radiation Absorbed Dose
🗑
|
||||
| Radiation | Emission and movement of energy through space.
🗑
|
||||
| Radiolucent | X-rays appear dark gray or black.
🗑
|
||||
| Radiopaque | X-rays appear white or light gray.
🗑
|
||||
| Rem | Unit for measuring dose equivalent.
🗑
|
||||
| Roentgen | (R). Unit for measuring exposure.
🗑
|
||||
| Secondary Radiation | Travels the opposite direction of original x-ray.
🗑
|
||||
| Sievert | (Sv). SI unit for measuring dose equivalent.
🗑
|
||||
| Soft Radiation | Limited penetrating power and unsuitable for exposing dental radiographs.
🗑
|
||||
| Wavelength | The distance between two crests on a wave.
🗑
