NRSB RRS study guide
NRSB RRS · Work through your exam, one topic at a time.
The NRSB Registered Radiologic Technologist (RRS) certification is a professional credential for radiographers who want independent, third-party verification of entry-to-practice competence in diagnostic radiography. It suits technologists who have completed formal radiography education and are building or advancing a clinical career, as well as those preparing for state licensure or employer credentialing requirements. The exam samples the full scope of practice rather than one modality: radiation protection and safety, radiographic equipment and image production, patient care and management, procedures and anatomy, image evaluation and quality assurance, and professional ethics and scope of practice. Expect multiple-choice items that mix recall of physics and anatomy with applied judgment - shielding decisions, exposure factor reasoning, patient-communication scenarios, and image-critique questions. The NRSB RRS study guide has 6 sections and about 1,618 words.
01Radiation Protection and Safety
This domain tests how you turn ALARA from a slogan into decisions: selecting exposure factors, shielding, monitoring dose, and recognizing regulatory limits. It favors applied judgment over memorized numbers.
291 words, about 1 min02Radiographic Equipment and Image Production
This domain tests the chain from generator to receptor: tube design, exposure factor effects, beam restriction, grids, and digital capture. Expect questions that connect a change in technique to image appearance and dose.
281 words, about 1 min03Patient Care and Management
This domain tests safe, respectful care across the encounter: identification, communication, consent, immobilization, monitoring, infection control, and contrast emergencies. It rewards sequence and documentation.
268 words, about 1 min04Radiographic Procedures and Anatomy
This domain tests projections, positioning landmarks, and anatomy visible on the image. You must know why a position is chosen, not just the name.
254 words, about 1 min05Image Evaluation and Quality Assurance
This domain tests systematic image review and the QC tests that keep equipment and practice stable. You must separate technical acceptability from diagnostic adequacy.
255 words, about 1 min06Professional Ethics and Scope of Practice
This domain tests legal and ethical conduct at the point of care: scope, delegation, consent, confidentiality, documentation, and reporting. The best answer usually protects the patient and stays within role.
