1Which three fundamental principles of radiation protection are set out by the ICRP?
A.Justification, optimisation and dose limitation
B.Detection, correction and prevention
C.Shielding, distance and inversion
D.Calibration, collimation and compensation
Explanation: The ICRP system of radiological protection rests on three principles: justification (the benefit must outweigh the harm), optimisation (keep doses as low as reasonably achievable), and dose limitation (individual doses must not exceed set limits). These underpin all clinical radiation protection.
2The ALARA principle in radiation protection stands for keeping doses:
A.As Low As Reasonably Achievable
B.Always Less than Annual Reference Allowance
C.At a Level Above Recommended Action
D.As Low As Radiographically Available
Explanation: ALARA stands for 'As Low As Reasonably Achievable', the practical expression of the optimisation principle. It requires that exposures be minimised taking account of economic and social factors, not reduced to zero at any cost.
3The SI unit of absorbed dose is the:
A.Gray (Gy)
B.Sievert (Sv)
C.Becquerel (Bq)
D.Coulomb per kilogram (C/kg)
Explanation: Absorbed dose is the energy deposited per unit mass of tissue and is measured in gray (Gy), where 1 Gy equals 1 joule per kilogram. The sievert is used for equivalent and effective dose, which weight absorbed dose for biological effect.
4Effective dose is expressed in sieverts because it accounts for:
A.The type of radiation and the radiosensitivity of the tissues exposed
B.Only the energy absorbed per unit mass
C.The number of radioactive decays per second
D.The exposure time alone
Explanation: Effective dose multiplies the absorbed dose by a radiation weighting factor and a tissue weighting factor, so it reflects both the type of radiation and the radiosensitivity of the exposed tissues. This allows whole-body risk from non-uniform exposures to be compared.
5According to the inverse square law, if the distance from a point X-ray source is doubled, the radiation intensity becomes:
A.One quarter of the original
B.One half of the original
C.Twice the original
D.Four times the original
Explanation: The inverse square law states that intensity is inversely proportional to the square of the distance. Doubling the distance (factor of 2) reduces intensity by a factor of 2 squared, that is to one quarter. This is why increasing distance is an effective protection measure.
6Which three practical methods most directly reduce occupational radiation dose to staff?
A.Time, distance and shielding
B.Filtration, collimation and grids
C.Contrast, density and resolution
D.Voltage, current and exposure time
Explanation: The three cardinal principles of practical protection are minimising time in the radiation field, maximising distance from the source, and using shielding. Together they directly limit the dose received by staff during procedures such as fluoroscopy.
7X-rays are produced in the X-ray tube when high-speed electrons strike the:
A.Anode target
B.Cathode filament
C.Glass envelope
D.Tube housing
Explanation: Electrons are boiled off the cathode filament, accelerated across the tube by the high voltage, and strike the anode target (usually tungsten). The sudden deceleration and inner-shell interactions at the target produce bremsstrahlung and characteristic X-rays.
8Increasing the kilovoltage peak (kVp) applied to an X-ray tube primarily increases the:
A.Energy (penetrating power) of the X-ray beam
B.Number of electrons boiled off the filament
C.Focal spot size
D.Tube rotation speed
Explanation: kVp controls the potential difference accelerating the electrons, which sets the maximum and average photon energy. Higher kVp produces a more penetrating beam with higher average energy, improving penetration while reducing subject contrast.
9The quantity of X-ray photons produced in an exposure is controlled mainly by the:
A.Milliampere-seconds (mAs)
B.Kilovoltage peak (kVp)
C.Total filtration
D.Grid ratio
Explanation: mAs is the product of tube current and exposure time and determines the number of electrons and therefore the number of X-ray photons produced. It is the primary control of radiographic density or image brightness and of patient dose for a given kVp.
10Added filtration (for example aluminium) is placed in the X-ray beam primarily to:
A.Remove low-energy photons that would only increase skin dose
B.Increase the number of low-energy photons reaching the patient
C.Sharpen the focal spot
D.Reduce the anode heel effect
Explanation: Added filtration preferentially absorbs low-energy (soft) photons that would be absorbed in superficial tissue and contribute to skin dose without reaching the image receptor. This 'hardens' the beam, raising its average energy and reducing patient dose.

About the AHPC Radiography QE Exam

The AHPC Diagnostic Radiography Qualifying Examination (QE) certifies that a foreign-trained diagnostic radiographer meets the standard required for registration with the Allied Health Professions Council (AHPC) to practise in Singapore. It is taken by applicants whose qualifications are not on the AHPC List of Recognised Qualifications and who have received an In-Principle Approval letter. The examination is a single 3-hour written paper of 200 single-best-answer multiple-choice questions arranged in 3 parts: Parts 1 and 2 cover radiation protection, radiobiology, patient care, general radiography and radiation sciences, while Part 3 covers radiological anatomy, imaging and instrumentation, special modalities such as CT, ultrasound, MRI, nuclear medicine, angiography and fluoroscopy, plus medical informatics and pathology. Candidates must pass all 3 parts to obtain an overall pass. The QE is administered by the Singapore Institute of Technology (SIT) on behalf of the AHPC.

AHPC Radiography QE Study Tips from Top Performers

1Anchor your radiation protection revision in the ICRP framework of justification, optimisation and dose limitation, and be able to convert between absorbed, equivalent and effective dose in their correct units.
2Drill standard radiographic projections and centring points until you can state the position, central ray and key evaluation criteria for each common view without hesitation.
3Understand how kVp, mAs and source-to-image distance change image contrast, density and patient dose, since exposure-factor reasoning recurs throughout Parts 1 and 2.
4Learn MRI safety zones, ferromagnetic hazards and contraindications thoroughly, as MRI safety questions in Part 3 expect precise, patient-safety-focused answers.
5Review contrast media types, indications and the recognition and management of contrast reactions, linking them to patient care and consent.
6Memorise the core Singapore regulatory facts: the Allied Health Professions Act, AHPC registration types, scope of practice and the ethical duties expected of a registered radiographer.
