Reviewed DHA public sources

DHA regulates radiology and radiographer practice through the Sheryan healthcare professional licensing pathway. Public DHA materials confirm CBT assessment may be required and describe diagnostic imaging professional licensing, scope, patient safety, radiation safety, contrast, MRI, and service standards. A separate public radiographer blueprint was not found in reviewed DHA sources, so this practice set uses a transparent radiographer-focused competency map rather than inventing category-specific logistics.

Sample DHA Radiology / Radiographer Practice Questions

Try these sample questions to review concepts for the DHA Radiology / Radiographer exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which action best applies ALARA during a repeat-prone chest examination?
A.Check positioning and breathing before exposure, collimate tightly, and use an optimized technique
B.Increase mAs for every repeat-prone patient
C.Expose before explaining the breath hold
D.Use the widest field to avoid clipping
Explanation: ALARA means justified imaging with optimized exposure and avoidable repeats prevented.
2What is the main dose benefit of tight collimation?
A.Detector exposure always becomes zero
B.Image markers become unnecessary
C.The beam becomes nonionizing
D.Less tissue is irradiated and less scatter is produced
Explanation: Collimation limits exposed volume and reduces scatter while preserving the diagnostic target.
3What should happen when pregnancy is possible before pelvis radiography?
A.Double the mAs to avoid repeat
B.Ask only after the image is taken
C.Pause and follow pregnancy screening and justification policy
D.Proceed because diagnostic radiation is always irrelevant
Explanation: Pelvic exposure in possible pregnancy requires screening, justification, and local procedure.
4How can staff reduce exposure during mobile radiography?
A.Use continuous fluoroscopy for a static image
B.Use distance, shielding when available, and clear warning before exposure
C.Stand beside the tube head
D.Let visitors hold the detector without protection
Explanation: Time, distance, shielding, and communication reduce occupational and public exposure.
5Why should unnecessary repeat radiographs be avoided?
A.They add patient dose without additional benefit
B.They remove scatter
C.They improve identity checks
D.They make consent unnecessary
Explanation: Repeats are justified only when the first image is nondiagnostic and the cause is corrected.
6Which patient needs extra dose optimization attention?
A.An adult with a wrist marker
B.A paper request form
C.A detector on charge
D.A neonate having a chest radiograph
Explanation: Children and neonates are more radiosensitive and need pediatric technique and immobilization.
7What is the purpose of a controlled area during x-ray exposure?
A.Replace side markers
B.Prevent all patient motion
C.Limit access so people not involved are protected
D.Make the image brighter
Explanation: Access control protects staff, visitors, and other patients from unnecessary exposure.
8Which principle explains lower exposure when staff step farther from a source?
A.Window width
B.Inverse square law
C.Doppler shift
D.Nyquist theorem
Explanation: Radiation intensity from a point source falls with the square of distance.
9Which practice helps avoid gonadal exposure on a pelvis exam?
A.Accurate centering and collimation to the required anatomy
B.Opening the field beyond the skin margins
C.Cropping after exposure only
D.Using no positioning checks
Explanation: Dose is reduced by limiting the beam before exposure, not by post-processing.
10What should a radiographer do if a requested exam seems unjustified?
A.Image the largest area just in case
B.Ask the patient to choose the exam
C.Delete the clinical history
D.Clarify with the radiologist or referrer before exposure
Explanation: Justification depends on a valid clinical question and an appropriate requested examination.

About the DHA Radiology / Radiographer Exam

The DHA radiology and radiographer licensing pathway is part of Dubai Health Authority healthcare professional regulation through Sheryan. DHA licensing materials require professional qualification review, primary source verification, good standing documentation, and a CBT assessment when applicable. This practice set is aimed at radiographer and radiology technologist competencies in diagnostic imaging services: radiation protection, projection radiography, CT, MRI safety, contrast safety, patient care, infection control, documentation, and professional practice in Dubai healthcare settings.

Exam sponsor: Dubai Health Authority (DHA). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

DHA public CBT guidance lists 150 multiple-choice questions for physician radiology categories; radiographer-specific public logistics were not found in reviewed sources.

Time Limit

3 hours in DHA public CBT guidance for physician radiology categories; confirm current Sheryan category scheduling.

Passing Score

65% is published for physician radiology categories in DHA CBT guidance; radiographer-specific public pass mark not found.

Exam / Certification Fees

DHA CBT guidance examples list USD 280 for physician radiology categories; confirm current title-specific fee in Sheryan.

DHA Radiology / Radiographer: Suggested Study Strategy

1Review DHA licensing steps, PQR title requirements, and diagnostic imaging service standards before booking.
2Practice image critique by checking identity, side marker, projection, anatomy coverage, rotation, exposure, and motion on every image.
3Use radiation protection principles in every scenario: justification, optimization, collimation, distance, shielding where policy supports it, and repeat avoidance.
4Know contrast and MRI red flags that require escalation before proceeding.
5For trauma and pediatric cases, prioritize safety, immobilization, dose optimization, and adapted positioning.

Frequently Asked Questions

Is the DHA radiology assessment a computer-based test?

DHA licensing is managed through Sheryan and public DHA assessment guidance describes computer-based testing when required. Candidates should confirm current booking and delivery details in Sheryan for their exact professional title.

How many questions are on the DHA radiographer exam?

Reviewed DHA public sources did not publish a separate radiographer item count. DHA CBT guidance lists 150 questions over 3 hours for physician radiology categories, so this page does not invent a radiographer-specific count.

What does this practice bank cover?

It covers radiographer and radiology technologist competencies: radiation safety, positioning, image quality, CT, MRI safety, contrast safety, mobile imaging, infection control, documentation, and professional ethics.

Where should candidates confirm eligibility?

Candidates should use DHA Sheryan and the current DHA Professional Qualification Requirements for title-specific eligibility, assessment, fee, and exemption rules.
