ALARA
As Low As Reasonable Achievable
Transformation of energy is?
Radiation
What kind of wave length do x-rays have?
Short
What is the most dangerous type of beam interaction?
Compton Scatter
Where does the x-ray come from when it is a diagnostic x-ray?
Above
Where does the x-ray come from when it is a fluoroscopy x-ray?
Below
What did Albert Einsten create?
Photoelectric Effect
What did Wilham Roentgen do?
Discovered x-ray
What did Thomas Edison do?
Fluoroscope tube; live x-ray
Characteristic x-ray produces what?
Ionizing radiation
Bremsstrahlung x-ray produces what?
ion beams, also makes them change direction
Name the x-ray internactions
classical, compton, photoelectric, uninterrupted
Name the types of x-rays?
characteristic and bremsstrahlung
Homogeneous
same
Heterogeneous
different
Cathode
Negative, electrons, filament tugstone,
Andeode
positive, rotating part, rotor
Calometer
restricts the size of the folospot
We use lead because
it has a high atomic number and gets rid of ionizing radiation
We use Pyrex glass because
it can with stand heat (due to interactions with electrons)
Filter
aluminum, gets rid of low x-rays
