Try these sample questions to test your Maharashtra HSC Radiology Technician (Vocational) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1X-rays used in diagnostic radiography are a form of:
A.Electromagnetic radiation of very short wavelength
B.Mechanical sound waves only
C.Visible light of long wavelength only
D.Ultrasonic compression waves
Explanation: Diagnostic X-rays are ionizing electromagnetic radiation with wavelengths much shorter than visible light, which is why they can penetrate tissues and expose image receptors.
2Who is credited with discovering X-rays in 1895?
A.Marie Curie
B.Wilhelm Conrad Roentgen
C.Thomas Edison
D.Henri Becquerel
Explanation: Wilhelm Conrad Roentgen discovered X-rays in November 1895 while experimenting with cathode-ray tubes — a foundational fact in radiology history taught at HSC vocational level.
3In a diagnostic X-ray tube, electrons are boiled off the heated filament by:
A.Photoelectric emission from the film
B.Compton scattering in the patient only
C.Thermionic emission
D.Pair production at diagnostic kV
Explanation: A heated cathode filament releases electrons by thermionic emission; those electrons are then accelerated toward the anode, where X-rays are produced.
4Most of the kinetic energy of electrons striking the X-ray tube anode is converted into:
A.Useful X-ray photons only
B.Ultraviolet light only
C.Sound energy only
D.Heat
Explanation: In diagnostic tubes, roughly 99% of electron kinetic energy becomes heat in the anode; only a small fraction becomes X-rays — a standard radiation-physics teaching point.
5Which exposure factor primarily controls the penetrating power (quality) of the X-ray beam?
A.kVp
B.mAs alone
C.Focal-spot size alone
D.Film brand alone
Explanation: Kilovoltage peak (kVp) sets the maximum photon energy and strongly influences beam quality/penetration. mAs mainly controls quantity (number of photons).
6mAs (milliampere-seconds) is the product of:
A.kVp and SID only
B.Tube current (mA) and exposure time
C.Grid ratio and focal spot only
D.Filtration thickness and OID only
Explanation: mAs = mA × exposure time. It controls the total number of electrons flowing across the tube and therefore largely the quantity of X-rays produced.
7According to the inverse-square law, if the distance from a point X-ray source doubles while output is unchanged, beam intensity becomes approximately:
A.Twice as high
B.Four times as high
C.One-fourth
D.One-half
Explanation: Intensity varies inversely with the square of distance. Doubling distance multiplies intensity by 1/4 (I2/I1 = (d1/d2)^2).
8Added filtration in the X-ray beam primarily:
A.Increases low-energy photons that only increase patient skin dose
B.Converts the beam into ultrasound
C.Eliminates all scatter generated inside the patient
D.Removes many low-energy photons that would mainly increase patient dose without improving the image
Explanation: Filtration hardens the beam by preferentially removing low-energy photons that would be absorbed in superficial tissues, reducing patient dose with relatively little loss of useful beam.
9The target (anode) material commonly used in general diagnostic X-ray tubes is:
A.Tungsten (often with rhenium alloy on the track)
B.Lead foil only
C.Pure aluminum only
D.Plastic polymer only
Explanation: Tungsten has a high atomic number and high melting point, making it suitable for the anode target; many rotating anodes use tungsten-rhenium alloy on the track.
10Bremsstrahlung (braking) radiation is produced when:
A.A free neutron is captured by hydrogen only
B.An incident electron is deflected by the nuclear field of a target atom and loses energy as an X-ray photon
C.Visible light is reflected from the collimator
D.Ultrasound reflects from soft-tissue interfaces
Explanation: Bremsstrahlung occurs when high-speed electrons are decelerated/deflected near target nuclei and lose kinetic energy as X-ray photons — the dominant production mechanism in diagnostic tubes.
