MHP Jobs

TL;DR
  • MHP Part II certification is administered by the American Board of Medical Physics (ABMP) via ExamSoft, not a generic testing center.
  • Employers hiring for these roles care most about the five 15%-weighted domains: Standards and Regulations, Structural Shielding, Radiation Oncology, Diagnostic...
  • The 2026 Part II fee is $690 by check or $715 through PayPal for a four-hour written exam.
  • Eligibility depends on a relevant graduate degree, supervised clinical experience, dual endorsements, and the MHP Training and Education Form.

The MHP Job Landscape

Certification in Medical Health Physics is a specialty credential issued through the American Board of Medical Physics, and it is built specifically for physicists who work in the radiation safety and clinical medical physics space rather than pure research or general medical physics. Because the Part II written exam tests applied knowledge across nine weighted content areas - from instrumentation to non-ionizing radiation - the jobs tied to this certification cluster around clinical radiation environments where regulatory compliance, shielding design, and equipment safety intersect.

If you are researching this credential for the first time, it helps to start with the fundamentals covered in What Is MHP? and MHP Meaning before mapping out job targets. This article assumes you already understand the basic identity of the credential and focuses on how it translates into hiring conversations.

Scope Note: This guide covers Part II, the written Medical Health Physics specialty examination. It does not cover Part I General Medical Physics content or the Part III oral examination, though both are part of the broader certification sequence that employers may reference in job postings.

Who Hires MHP-Certified Physicists

Positions that reference Certification in Medical Health Physics, or that treat it as a strong preferred qualification, tend to fall into a few recurring categories:

  • Hospital radiation oncology departments - reviewing treatment planning shielding, machine commissioning, and regulatory documentation.
  • Diagnostic imaging and nuclear medicine departments - overseeing equipment quality assurance, dose optimization, and license compliance for molecular imaging programs.
  • Radiation safety offices at academic medical centers - where Standards and Regulations knowledge and shielding calculations are used daily.
  • Consulting firms that perform structural shielding design and licensing support for new or renovated imaging and treatment suites.
  • Regulatory and compliance roles at state or institutional radiation control programs, where familiarity with the standards tested on Part II is directly relevant.

Because the certification pathway allows qualified Certified Health Physicists a separate direct-to-oral route into Part III, some employers specifically look for candidates who already hold CHP status alongside MHP credentials - a signal of cross-trained radiation safety expertise.

How the Nine Domains Show Up in Daily Work

The value of this certification to an employer is really the value of the blueprint itself. Each domain corresponds to a real job function, which is why hiring managers in this niche often ask interview questions that map almost directly onto exam content. A full breakdown of weighting and topics lives in MHP Exam Domains 2026: Complete Guide to All 9 Content Areas, but here is how the heaviest domains translate to on-the-job responsibilities.

Standards and Regulations (15%)

Employers expect fluency in the regulatory frameworks that govern radiation-producing equipment and licensure in clinical settings.

  • Writing or reviewing compliance documentation
  • Interfacing with regulatory inspectors

Structural Shielding (15%)

This domain underpins consulting and facility-planning roles, where physicists calculate barrier requirements for new vaults, treatment rooms, and imaging suites.

  • Shielding calculations for linear accelerators and imaging equipment
  • Room design reviews before construction sign-off

Radiation Oncology (15%)

Hospital-based roles frequently require hands-on knowledge of treatment machine safety, commissioning support, and dose delivery verification.

  • Machine acceptance and safety testing
  • Treatment planning system oversight from a safety standpoint

Diagnostic Imaging and Nuclear Medicine (15% each)

Together these two domains cover 30% of the blueprint and correspond to imaging physics and molecular imaging safety positions.

  • Equipment QA programs for CT, fluoroscopy, and nuclear medicine cameras
  • Radiopharmaceutical handling and dose optimization

The remaining domains - Instrumentation (10%), Laboratory Design, Radiation Biology, and Non-ionizing Radiation (5% each) - round out a well-prepared candidate's profile and often appear in interview scenarios about lab setup, biological dose effects, or non-ionizing hazards like MRI fields.

Key Takeaway

Five domains - Standards and Regulations, Structural Shielding, Radiation Oncology, Diagnostic Imaging, and Nuclear Medicine - make up 75% of the Part II blueprint and roughly 75% of what hiring managers in this field expect you to know cold.

Getting From Eligibility to Employment

Before you can put "MHP" after your name on a resume, you need to satisfy ABMP's eligibility structure: a relevant graduate degree, degree- and residency-dependent supervised clinical experience, endorsements from a board-certified physicist and a board-certified physician, and a completed MHP Training and Education Form. These requirements are detailed in full at MHP Requirements 2026: Eligibility, Prerequisites & How to Qualify, and they matter for job planning because many clinical residency or fellowship positions are structured specifically to generate the supervised experience this eligibility path requires.

The usual sequence is Part I credit (or an approved waiver), then Part II, then Part III. Employers who list "MHP-certified" as a requirement are almost always referring to completion of this full sequence, though some job postings for entry-level clinical physicist roles will accept "actively pursuing" status if a candidate has cleared Part I and is working through the supervised experience needed for Part II eligibility.

Exam Mechanics That Affect Your Job Timeline

Job seekers often underestimate how much the mechanics of Part II shape a realistic hiring timeline. The exam is administered on site through ExamSoft on the candidate's own compatible computer at a designated venue, runs four hours, and mixes single-answer multiple choice, matching, choose-all-that-apply, and shared-stem Type S questions. Passing is determined through a Modified Angoff standard-setting process rather than a fixed percentage cutoff - a distinction covered more fully in MHP Passing Score 2026: Exactly What You Need to Pass.

Budget accordingly: the 2026 Part II fee is $690 by check or $715 through PayPal. A complete cost breakdown, including how this fits with other steps in the certification sequence, is available in MHP Certification Cost 2026: Complete Pricing Breakdown. Because ABMP publishes an information booklet (most recently revised May 2025) with scheduling and blueprint details, candidates planning a job start date should check MHP Exam Dates 2026: Testing Windows, Deadlines & Scheduling before committing to an offer contingent on certification completion.

Realistic Timing: If a job offer is contingent on passing Part II, factor in registration lead time, the four-hour exam itself, and the possibility of a retake - Part II pass rates were 44% in 2023, 60% in 2024, and 57% in 2025, so a first attempt is not guaranteed to clear the bar.

Building a Domain-Based Study Timeline

Generic study techniques only matter here to the extent they help you allocate limited time across nine unevenly weighted domains. A practical approach is to schedule review blocks proportional to blueprint weight, front-loading the five 15% domains before touching the lighter 5% and 10% areas.

Weeks 1-2

Standards and Regulations + Structural Shielding

  • Work through regulatory citation questions and shielding calculation problems since these two domains combine for 30% of scored content
Weeks 3-4

Radiation Oncology + Diagnostic Imaging

  • Practice shared-stem Type S questions, which frequently appear in clinical scenario domains
Week 5

Nuclear Medicine

  • Focus on molecular imaging dosimetry and radiopharmaceutical handling scenarios
Week 6

Instrumentation, Lab Design, Radiation Biology, Non-ionizing Radiation

  • Cover these lighter-weighted domains together since each is only 5-10% of the blueprint

Where Certification Fits Into Pay and Career Value

Certification alone does not set your salary - your employer, region, and clinical setting do - but it does function as a gate for many radiation safety and clinical physics roles that require documented, board-recognized competency. For a full discussion of how compensation tends to vary across settings without relying on invented figures, see MHP Salary Guide 2026: Complete Earnings Analysis. If you're still deciding whether the time and cost investment makes sense given your career goals, Is the MHP Certification Worth It? Complete ROI Analysis 2026 walks through the tradeoffs in more depth.

Maintaining the credential also has ongoing career implications: certification renews every five years with 125 CE credits, including at least 65 Category 1 credits and no more than 60 Category 2 credits. Employers in regulated clinical environments often track this renewal cycle closely, since lapsed certification can affect a facility's own compliance standing.
