Interaction Flashcards
The reduction in radiation intensity as a result of absorption and scattering
Attenuation
X-ray disappears
Absorption
Partial absorption
Attenuation
Absorbs many x-rays
Radiopaque
Absorbs few x-rays
Radiolucent
What are the 2 factors that determine attenuation?
Atomic number(Z#) - number of protons in the nucleus
Tissue Density
Produced whenever x-rays interact with any type of matter
Secondary radiation
Completely absorbed and energy emitted
Secondary radiation
A type of secondary radiation that only loses some energy and continues in another direction
Scatter radiation
Primary radiation has what type of energy?
Secondary?
High
Low
Occurs within the patient
Secondary radiation
Results in higher patient dose
Secondary radiation
What type of radiation happens to technologists?
Scatter radiation
Passes through the tube housing
Leakage radiation
Passes through the window
Primary radiation
Produced when primary interacts with matter
Secondary radiation
Primary and secondary rays which exit the patient and interacts with technologist
Remnant radiation
Occurs anytime radiation interacts with matter
Secondary radiation
Increases with the use of increased kVp
Secondary radiation
Travels at the speed of light
Secondary radiation
