"High-velocity electrons (e-) that completely avoid the orbital electrons as they pass through a
tungsten atom, yet come close enough to the nucleus of the atom to come under the influence
of its positively charged electric field (P+), will produce what type of X-rays?
A.) Characteristic x-rays
B.) Compton X-rays
C.) Bremsstrahlung X-rays
D. ) Thompson X-rays - CORRECT ANSWER=> (C) Bremsstrahlung X-rays
Explanation:
Bremsstrahlung literally means "braking." When a high-velocity electron passes through a
tungsten atom, avoiding the electrons, yet coming close enough to the nucleus to be affected by
the positively charged electric field of the nucleus, the change of direction, or braking, causes a
release of x-rays known as Bremsstrahlung."
"What is the relationship of LET and biological damage?
A.) They increase in direct proportion.
B.) They are inversely proportional.
C.) There is no relationship.
D.) There is a nonlinear nonthreshold relationship - CORRECT ANSWER=> (A) They increase in
direct proportion.
Explanation:
The LET refers to the linear energy transfer, the amount of energy transferred by ionizing
radiation per unit length of tissue traveled. LET is variable between radiation types. High-
ionization radiation, including neutrons and alpha particles, cause more biological damage than
radiation with a lower LET, including x-rays and gamma rays."
"Which skull position is most useful to demonstrate the sphenoid sinuses?
A.) AP axial
