Question 1
X-rays are a form of:
A) Gamma radiation
B) Electromagnetic radiation with high energy and short
wavelength
C) Particulate radiation
D) Radio waves
,Page 2 of 90
Answer: B
*Rationale: X-rays are high-energy electromagnetic radiation
with wavelengths between 0.01 and 10 nanometers, produced
when high-speed electrons interact with a metal target.*
Question 2
The cathode in an X-ray tube:
A) Contains the target (anode) and emits X-rays
B) Is the negative electrode that produces and focuses the
electron beam
C) Converts electrons into X-rays
D) Filters the X-ray beam
Answer: B
Rationale: The cathode consists of a filament (usually tungsten) that
emits electrons when heated (thermionic emission). These electrons
are focused toward the anode.

Question 3
The anode in an X-ray tube:
A) Is the positive electrode that serves as the target for electrons,
producing X-rays
B) Emits electrons
C) Controls the tube current
D) Houses the collimator
Answer: A
Rationale: The anode is the positive electrode; electrons strike the
target (usually tungsten) and produce X-rays via Bremsstrahlung
and characteristic interactions.
Question 4
What is the primary difference between Bremsstrahlung and
characteristic X-rays?
, Page 4 of 90
A) Bremsstrahlung X-rays result from electron-nucleus interactions;
characteristic X-rays result from electron-shell interactions
B) Characteristic X-rays are produced by all X-ray tubes;
Bremsstrahlung are not
C) Bremsstrahlung X-rays have discrete energies; characteristic
X-rays have continuous spectrum
D) There is no difference
Answer: A
Rationale: Bremsstrahlung (“braking radiation”) occurs when an
electron is deflected by the nucleus, emitting a continuous spectrum
of X-rays. Characteristic X-rays occur when an electron knocks out
an inner-shell electron, and another electron fills the vacancy,
emitting a discrete energy X-ray.
Question 5
The kVp (kilovoltage peak) controls:
