- ABR-NMP-P2 covers five domains: safety/ethics, PET & hybrid, single-photon systems, radiation measurements, and clinical procedures.
- Passing Part 2 alone does not confer board certification; full certification requires Parts 1, 2, and 3.
- Board eligibility lasts six full calendar years from residency completion or Part 2 approval, whichever comes first.
- Employers evaluating nuclear medical physicists should distinguish ABR pathways from ABSNM, a separate certifying body.
What the ABR-NMP-P2 Credential Signals to Employers
The Nuclear Medical Physics Part 2 Qualifying Examination is administered by the American Board of Radiology as one stage in a multi-part certification process. When a hiring manager at a hospital, academic medical center, or imaging vendor sees "passed ABR-NMP-P2" on a CV, it signals that the candidate has cleared a rigorous, criterion-referenced assessment covering radiation safety, PET and hybrid imaging, single-photon systems, radiation measurement instrumentation, and clinical nuclear medicine procedures - the exact domain structure detailed in our complete guide to all five content areas.
It is important to be precise about what this milestone means. Passing Part 2 does not, by itself, confer board certification. Full initial certification in medical physics requires successfully completing Parts 1, 2, and 3. For employers and candidates alike, understanding this sequence matters when evaluating where someone stands in their career trajectory - a person who has passed Part 2 is board-eligible, not yet board-certified. Details on this distinction and what "board eligible" actually means are covered in our certification overview.
Who Hires Candidates Working Toward ABR-NMP-P2
Because the credential is tied to the nuclear medical physics specialty specifically, the employer landscape tends to center on organizations that operate nuclear medicine, PET, and SPECT/CT programs. These typically include:
- Hospital-based nuclear medicine and molecular imaging departments that need physicists to oversee dose calibrator calibration, survey meter programs, and camera quality control.
- Academic medical centers with CAMPEP-accredited residency programs, which employ board-eligible and board-certified physicists as clinical faculty and residency mentors.
- Radionuclide therapy and theranostics programs, where expertise in dosimetry and therapy procedures overlaps directly with Domain 5 content.
- Regulatory and radiation safety offices within health systems, where knowledge of occupational and public safety, shielding, and ethics (Domain 1) is directly applicable.
- Equipment manufacturers and consulting firms that need physicists familiar with PET/CT and SPECT/CT acceptance testing and quality control.
In nearly all of these settings, the underlying eligibility requirement is the same: completion of, or being on track to complete, a CAMPEP-accredited residency or Doctor of Medical Physics program. Our requirements article walks through the full eligibility pathway in detail.
How the Five Exam Domains Map to Daily Job Duties
One reason the Part 2 exam is such a meaningful credential for hiring purposes is that its content guide mirrors the actual responsibilities of a working nuclear medical physicist. Each domain corresponds to a recognizable slice of clinical or safety work.
Domain 1: Radiation Protection, Safety, Professionalism and Ethics
Covers internal, fetal, and CT dosimetry, occupational and public safety, shielding design, and professional ethics - work that maps directly onto radiation safety officer duties and regulatory compliance roles.
- Shielding calculations for hot labs and imaging suites
- Occupational dose monitoring programs
Domain 2: PET & Hybrid
Includes PET detector physics, acquisition, reconstruction, attenuation/random/scatter corrections, quantification, PET/CT integration, and acceptance/annual testing - the core skill set for physicists supporting oncology and theranostics imaging.
- PET/CT quality control programs
- Quantitative accuracy troubleshooting
Domain 3: Single Photon Imaging Systems
Covers scintillation and solid-state cameras, intrinsic/extrinsic performance testing, collimation, digital and dynamic imaging, SPECT, and SPECT/CT - the daily bread of gamma camera quality assurance.
- Collimator selection and uniformity testing
- SPECT/CT acceptance and routine QC
Domain 4: Radiation Measurements
Dose calibrators, well counters, survey meters, and thyroid probes, plus statistical tests, error propagation, and minimum detectable activity - the instrumentation backbone every nuclear medicine department relies on.
- Dose calibrator constancy and accuracy testing
- Chi-square and statistical analysis of counting data
Domain 5: Clinical Procedures
Cardiac, pulmonary, tumor, bone, brain, thyroid, lymphatic, radionuclide therapy, and brachytherapy procedures - direct clinical support work performed alongside nuclear medicine physicians and technologists.
- Protocol optimization for common studies
- Radionuclide therapy dosimetry support
Because these domains are not published with fixed percentage weights, candidates and hiring managers alike should treat them as equally important pillars rather than assume any single area dominates the exam or the job. For a deeper breakdown of how to study each one, see our study guide for passing on the first attempt.
Exam Mechanics That Affect Your Job Timeline
Job seekers and current employees pursuing this credential should plan around the ABR's administration calendar and format, since these directly affect when you can claim board-eligible status on a resume.
- The exam is a remotely proctored, computer-based test administered in one session, registered through myABR.
- Format is predominantly multiple-choice, with some image-location items requiring you to identify an anatomical site, equipment component, or graph region.
- The 2026 remote-exam guide specifies 130 questions with 4 hours 1 minute of answering time, plus 20 minutes of tutorial/practice and 25 minutes of break allowance, for 4 hours 46 minutes total allotted time.
- The exam is closed book, though an embedded or ABR-approved handheld calculator and a compliant physical whiteboard are permitted; the whiteboard must be cleared at both the start and end of the session.
- The Part 2 exam fee is USD 640, due at registration, separate from the USD 250 initial application fee.
These logistics matter for job planning because a failed attempt requires retaking the entire exam, and there is a one-time USD 250 re-examination fee after a first-attempt failure. Delays here can push back your ability to accept positions that specify board-eligible or board-certified status as a hard requirement. Full fee breakdowns are covered in our certification cost breakdown, and exam-day specifics are covered in our difficulty guide.
Key Takeaway
Build your job search timeline around the application window (first business day in February through March 31, 2027 for the current cycle), registration invitations in May 2027, and the published exam date of August 11, 2027 - see our exam dates and deadlines guide for scheduling details.
Eligibility Pathway and Board-Eligible Status
Standard Part 2 eligibility requires having passed both the General and Clinical sections of Part 1, and completing (or being on track to complete) a CAMPEP-accredited residency or Doctor of Medical Physics program by August 31 of the exam year. Residency must begin within 10 years of passing Part 1. Once you pass Part 2, your board eligibility lasts six full calendar years from residency completion or Part 2 approval, whichever occurs first - this is the window during which you should plan to complete Part 3 and pursue positions that count on your progression toward full certification.
Physicists already certified in another specialty have a separate additional-specialty pathway involving ABR-approved prospective, supervised clinical training while they maintain their existing certification. This route is common for physicists transitioning into nuclear medical physics from a related specialty, and it affects how a hiring department might structure a transitional role.
Studying for Domains While Working Clinically
Many candidates pursue ABR-NMP-P2 while already working in a residency or junior physicist role, which means study time is limited and must be deliberately scheduled around clinical duties. Rather than generic study advice, sequence your preparation around the domains you encounter least often on the job. If your daily clinical rotation is heavy on SPECT/CT quality control (Domain 3) but light on radionuclide therapy dosimetry (part of Domain 5), weight your independent study time toward the latter.
Radiation Safety and Radiation Measurements
- Review shielding calculations, occupational dose limits, and dose calibrator QC procedures you may not perform daily
- Work through error propagation and chi-square statistical problems
PET & Hybrid and Single Photon Systems
- Focus on reconstruction and attenuation correction math if your department uses vendor-automated workflows
- Practice collimator and camera performance troubleshooting scenarios
Clinical Procedures and Full Review
- Cross-reference therapy, cardiac, and brain protocols against clinical guidelines
- Run timed practice sessions matching the exam's answering-time structure
Our practice test platform offers original, domain-mapped practice questions and worked calculations designed to reinforce exactly this kind of targeted review, without relying on recalled or secure exam content. Pair that with our one-page review of must-know facts for quick refreshers between clinical shifts.
ABR-NMP-P2 vs. ABSNM: Two Distinct Pathways
Candidates researching job requirements sometimes encounter both ABR and ABSNM credentials in postings for nuclear medicine physics roles. These are separate certifying organizations with distinct examination pathways, and they should not be treated as interchangeable when evaluating a job posting or a candidate's qualifications.
| Aspect | ABR-NMP-P2 (this article's scope) | ABSNM |
|---|---|---|
| Certifying body | American Board of Radiology | American Board of Science in Nuclear Medicine (separate organization) |
| Position in pathway | Part 2 of a three-part ABR medical physics certification sequence | Independent certification process under its own body |
| Relationship | Distinct pathway; not a substitute for the other | Distinct pathway; not a substitute for the other |
When reviewing job postings, confirm which credential the employer is actually requiring rather than assuming the two are synonymous. For more on how the ABR credential fits into the broader landscape, see our explainer on what ABR-NMP-P2 is and our page on what the designation means.
Salary Context for Nuclear Medical Physicists
Compensation data for medical physicists is periodically gathered through surveys such as those published by the American Association of Physicists in Medicine (AAPM). When researching salary expectations, pay close attention to two things: the survey year and the population sampled. Broad medical physics salary surveys typically cover physicists across multiple specialties and career stages, and they are not the same as a nuclear-specialty-specific figure. It's also important to distinguish medical physicists from nuclear medicine technologists, since job boards and salary aggregators sometimes conflate the two very different roles and credentialing requirements.
Rather than quoting a single number here, use current AAPM survey data as your primary source and read it alongside your own factors - years of experience, geographic market, academic versus clinical setting, and whether you hold full board certification versus board-eligible status. Our salary guide walks through how to interpret this kind of survey data responsibly, and our ROI analysis looks at the broader value proposition of pursuing full certification.
Maintaining the Credential for Long-Term Career Stability
Once a physicist completes the full three-part certification pathway and earns board certification, ongoing employability depends on maintaining that certification through ABR Continuing Certification. This includes professional standing through licensure or attestation, 75 qualifying Category 1 CME, CAMPEP-accredited CE, or Self-Directed Educational Project credits per rolling three-year period, and one Practice Quality Improvement project or qualifying activity per rolling three-year period. Newly certified diplomates first meet these education and improvement requirements in year four.
Medical physics Online Longitudinal Assessment participation requires answering at least 52 questions per maintained certificate annually, with the passing standard met in year five of the five-year cycle, or alternatively passing a Continuing Certification Exam in year four or five. The annual medical physics Continuing Certification fee is USD 205. These maintenance obligations are separate from the process of passing Part 2 itself, but they matter for long-term career planning since many employers expect continuously maintained certification status for senior clinical physicist roles.
For candidates still preparing, understanding the passing standard used for Part 2 - a criterion-referenced pass/fail decision against an established standard rather than a curve - can reduce exam-day anxiety. See our passing score guide for details, and our pass rate analysis for how to interpret ABR's published results responsibly. If you're just starting to research this credential from scratch, our training overview and our main practice test resource are good starting points before diving into domain-specific study.
Frequently Asked Questions
Passing Part 2 makes you board-eligible, not board-certified. Full initial certification requires passing Parts 1, 2, and 3. Many entry-level and junior clinical roles accept board-eligible candidates, but check each posting's specific requirement.
Hospital nuclear medicine and molecular imaging departments, PET/SPECT equipment vendors, theranostics and radionuclide therapy programs, and radiation safety offices tend to prioritize the nuclear specialty because the exam's five domains map directly onto those departments' daily instrumentation and safety work.
Board eligibility lasts six full calendar years from residency completion or Part 2 approval, whichever occurs first, giving candidates a defined window to complete Part 3 and secure a position aligned with full certification.
No. ABR-NMP-P2 is administered by the American Board of Radiology as part of its medical physics certification sequence, while ABSNM is a separate certifying body with its own independent process. Employers should treat them as distinct credentials.
A failed attempt requires retaking the entire Part 2 examination; there is a one-time USD 250 re-examination fee after a first-attempt failure. Plan your job search timeline with this possibility in mind, particularly around application and registration windows.
