The Canadian Association of Medical Radiation Technologists (CAMRT) certification examination tests your competency across the full scope of medical radiation technology practice. The exam covers five major domains: radiation physics, radiographic imaging, radiation protection, patient care, and equipment operation and quality assurance.
Understanding the breadth of the CAMRT exam is the first step toward effective preparation. The questions below reflect the real exam blueprint, and this free PDF gives you printable practice you can take anywhere.
Questions in this domain assess your knowledge of X-ray production, beam quality, and the attenuation of radiation as it passes through matter. You need to understand how kilovoltage peak (kVp) and milliampere-seconds (mAs) affect the X-ray beam, as well as the photoelectric effect and Compton scatter in biological tissues.
This domain covers patient positioning for all major body regions, the selection of appropriate exposure factors, and principles of image quality including spatial resolution, contrast, and noise. Digital radiography — including computed radiography (CR) and direct digital radiography (DR) — is heavily tested. You should know how histograms and exposure indicators work, and how post-processing affects image appearance without altering patient dose.
CAMRT candidates must demonstrate a thorough understanding of radiation protection principles. This includes occupational dose limits set by the Canadian Nuclear Safety Commission (CNSC), the ALARA principle (As Low As Reasonably Achievable), primary and secondary shielding calculations, and personnel dosimetry devices such as thermoluminescent dosimeters (TLDs) and optically stimulated luminescence (OSL) dosimeters.
Patient care questions address informed consent, effective communication with diverse patient populations, immobilization techniques, and the safe administration of contrast agents. You are expected to recognize and respond to contrast media reactions and apply standard precautions for infection control.
This domain tests knowledge of radiographic and fluoroscopic equipment operation, including automatic exposure control (AEC), grids, image intensifiers, and flat-panel detectors. Quality assurance protocols — including sensitometry, kVp accuracy testing, and half-value layer (HVL) measurement — are also assessed.
Passing the CAMRT exam grants national certification, but you must also register with your provincial licensing body (e.g., CMRTO in Ontario, ARDTBC in British Columbia) before practicing. Provincial requirements may include additional jurisprudence exams or documentation. Always confirm the specific requirements for your province.
Print the PDF and work through each question without referring to notes. Time yourself — the real CAMRT exam is computer-based with a set time limit, so practicing under timed conditions builds exam stamina. After completing a section, review every incorrect answer and trace it back to the relevant domain in your study materials.
Focus extra attention on radiation physics and radiation protection, which together account for a large portion of exam marks. Use the CAMRT Competency Profile document (available on the official CAMRT website) as your master checklist to confirm you have covered every competency statement before your exam date.
Candidates who pass on their first attempt typically study for eight to twelve weeks. Start with the CAMRT Competency Profile to identify which knowledge areas carry the most weight, then build a weekly study schedule that cycles through all five domains. Use flashcards for anatomy and physics formulas, and work through case-based questions to practice clinical reasoning.
Join study groups or online communities of MRT candidates — peer discussion of difficult concepts accelerates learning far more than passive re-reading. On exam day, flag questions you are unsure about and return to them after completing the easier items. Never leave a question blank; there is no penalty for guessing on the CAMRT exam.
