Radiology Board ReviewThe shorter the wavelength the stronger or weaker the energy ? - ANS stronger
What do x-rays produce ? - ANS ionization
What is the ejection of an electron from an atom and produces a charged ion pair or free radical
? - ANS Ionization
What type of electricity moves negative electrons along a wire to positive charged electrons and
changes direction 60 times per second ? - ANS AC Electricity
One second equals how many impulses of x-rays and 1/4 second equals how many impetuses
of x-rays ? - ANS 1sec.=60 impulses of x rays
1/4 sec.= 15 impulses of x-rays
What describes the number of electrons flowing ? - ANS Amperes = mA
What is the potential differences between the negative and positive and the speed or force of
the moving electrons towards the positive charge ? - ANS Voltage = kVp
What is the quantity of the beam ? - ANS The number of xrays given off in a period of time
What is the quality of the beam ? - ANS The penetrating nature / power of the xrays photons /
involves wavelength
What three things affect the quantity of an x-ray ? - ANS mA, Exposure time, Distance
What two things affect the quality and quantity of an x-ray ? - ANS kVp, Aluminum filtration
What does the aluminum filtration do ? - ANS decreases the number of photons
removes softer dangerous photons
hardens the beam
As the distance of a x-ray beam spreads what happens to the number of photons ? - ANS the
number of photons decreases
The more the photons the more or less the density ? - ANS the MORE density
more energy= more blackness
What five things affect density of an x-ray ? - ANS mA, exposure time, kVp, increases
filteration decreases, distance decreases
