Ionizing Radiation Flashcards
What are the two types of ionizing radiation imaging basics?
Transmission and Emission
What does the tomagraphic mode of ionizing radiation?
Tomographics modes which produce axial slices rather than @D projections of object.
What spectrum is ionizing radiation in and what types of waves make up ionizing radiation?
Ionizing radiation is on the electromagnetic spectrum. X-Rays, Gamma Rays, Beta Radiation, Alpha Particles.
How do you measure ionizing radiation?
J/Kg in air or Gy
Do all forms of ionizing radiation produce the same forms of biological damage?
No, similiar doses of different particles will produce a variety of biological effects.
What are the factors that effect radiation damage?
Dose Rate and dose fraction.
What is the most toxic form of ionizing radiation?
Neutrons and heavy charged particles can cause multiple damage points to molecule and limit repair.
What are the factors that effect radiation damage?
- Type of Tisse
- Phase of the Cell Cycle
- Volume of irradiation
- Oxygen level of the tissue
