Bushong Chapter 1-4
Wavelength - answer distance from one crest to another
Amplitude - answer one half the range from crest to valley over which the sine wave
varies
Frequency - answer number of wavelengths that pass a point of observation per second
wavelength and frequency - answer Both are inversely proportional
Wave equation - answer velocity = frequency x wavelength
electromagnetic wave equation - answerf=c/λ
energy of a photon and its frequency - answerThey are directly proportional
diagnostic ultrasound is part of the electromagnetic spectrum - answerfalse
Refraction - answerBending of light
wave particle duality - answerstates that light and matter can behave as both a wave
and a particle
difference between radiopaque and radiolucent - answerLight allows to be transmitted
but other does not allow to be transmitted
inverse square law - answerdescribes the relationship between radiation intensity and
distance from the radiation source
Law of Conservation of Matter - answermatter cannot be created or destroyed
Law of Conservation of Energy - answerEnergy cannot be created or destroyed
Plancks Quantum Theory - answerΔE = hf
Theory of Relativity - answerexplains how space and time are linked for objects that are
moving at a consistent speed in a straight line
matter - answeranything that has mass and volume (occupies space)
mass - answermeasurement of how much matter is in an object
, energy - answerthe capacity for doing work
kinetic energy - answerthe energy an object has due to its motion
potential energy - answerenergy that is stored in an object due to its position relative to
some zero position.
Electromagnetic energy - answerform of energy that is reflected or emitted from objects
in the form of electrical and magnetic waves that can travel through space
Mass energy equivalence - answerthe principle that anything having mass has an
equivalent amount of energy (e=mc^2)
radiation - answerthe emission and propagation of energy in the form of waves, rays or
particles.
Ionizing radiation - answergives off energy by knocking electrons off atoms, which
causes the atoms to have a charge.
ionization - answerprocess of loosing or gaining an electron, which converts electrically
neutral atom to a charged atom
Ion pair - answerpositive ion and a negative ion temporarily bonded together by the
electrostatic force of attraction between them
Sources of ionizing radiation? - answerNatural environmental radiation (3mSv/year)
Man made radiation (3.2 mSv/year)
Mili sievert
components of natural environmental radiation - answeralpha radiation, uranium,
radium, radon, polonium
Largest manmade source of ionizing radiation is - answerx-ray
NCRP - answerNational Council on Radiation Protection
Who discovered x-rays and when? - answerWilhelm Conrad Roentgen on November 8,
1895
What was the first radiograph? - answerhand of Wilhelm roentgens wife
kVp - answerregulates the speed of electrons traveling from the cathode to the anode
and determines the penetrating ability of the x-ray beam.
mAs - answermeasure of radiation produced over a set amount of time (seconds) via an
x-ray tube
