State Overview
New Hampshire licenses radiology as more than a single credential. Alongside the general radiologic technologist license, it recognizes 5 separate base licenses (Computed Tomography (CT) Technologist, MRI Technologist (Magnetic Resonance Technologist), Radiation Therapist, Nuclear Medicine Technologist, and Sonographer (Diagnostic Medical Ultrasound)), plus a limited-permit tier (Limited X-Ray Machine Operator).
A few other modalities are not licensed by the state at all, rather than carrying their own New Hampshire license. The specialty section below covers each, including where a single-modality candidate may not be placeable.
Across radiology, ARRT certification is the national credential that anchors state licensure. A license you hold in another state does not transfer automatically, so you apply directly to New Hampshire's licensing board for each assignment.
General Requirements
If you perform radiology procedures in New Hampshire, the baseline below applies regardless of where you trained or which modality you work in.
- National certification: an active ARRT credential is the prerequisite the state license is built on. The state credential sits on top of ARRT, not instead of it.
- Credential required: ARRT certification and registration in Radiography; completion of an approved radiography course of study; age 18+; high school diploma or equivalent.
- Scope of the base license: Comprehensive set of diagnostic radiographic procedures using external ionizing radiation.
- Verification: ARRT or direct board verification.
Fees & Credentials
New Hampshire issues more than one radiology credential, so fees vary by what you actually do. The table below is one row per state-recognized credential.
| Credential | Application | Renewal | Cycle |
|---|---|---|---|
| Radiographer (General Diagnostic Radiologic Technologist) | $155 | $155 | Every 2 years |
| Computed Tomography (CT) Technologist | $155 | $155 | Every 2 years |
| MRI Technologist (Magnetic Resonance Technologist) | $155 | $155 | Every 2 years |
| Radiation Therapist | $155 | $155 | Every 2 years |
| Nuclear Medicine Technologist | $155 | $155 | Every 2 years |
| Sonographer (Diagnostic Medical Ultrasound) | $155 | $155 | Every 2 years |
| Limited X-Ray Machine Operator | $155 | $155 | Every 2 years |
There is no state fee line for Medical Physicist, because New Hampshire does not license those modalities. Their absence from the table is the point, not an omission.
$170 (Plc 1002.26) — both the doc ($158) and the live page ($155) are superseded. The background check is billed separately by NH State Police.
Renewal & Continuing Education
- Renewal cycle: every 2 years, based on date of issuance.
- Continuing education: your CE is whatever ARRT requires to keep your credential active. New Hampshire does not appear to add its own hour mandate for the general license.
Getting Licensed
Radiology licensure is ARRT-primary, so the path is shorter than the multi-step endorsement other professions run. For most candidates it is four steps:
- Hold the right ARRT credential for the work you will do (Radiography for general x-ray; the matching post-primary credential for a modality the state licenses).
- Complete a board-approved program if the state requires one for your credential.
- Apply to New Hampshire Office of Professional Licensure and Certification through the application portal.
- Have ARRT verify your credential to the board directly. You do not self-attest the certification.
Common slip-ups travelers hit here: submitting incomplete verification from previous state, ARRT verification must include current license number and expiration date; missing details trigger rejection and restart.
Processing & Timing
Board processing time is how long the board takes once it has a complete application. In New Hampshire: About 120 days. Boards rarely publish a guaranteed turnaround, so treat this as a planning number rather than a promise.
Recommended lead time before your start date is the total runway, and it runs longer than the board's processing window. Start the application as early as you can, because your ARRT verification has to reach the board before it can act.
If you need more than one credential here, for example a base license plus an add-on authorization, they may process as separate items rather than in one pass. Do not assume you can layer the second credential on at the last minute.
New Hampshire processing times are predictable (4-12 weeks) but not rapid. Temporary license accelerates start (8-14 days) and bridges the gap to permanent license, reducing assignment cancellation risk significantly.
Specialty Differences
Most of the radiology family in New Hampshire runs on the general license. A handful of credentials genuinely diverge, and those are the ones worth reading closely. Below is one subsection per real difference, then roll-up lines for everything else.
Computed Tomography (CT) Technologist
Divergence: separate license. Computed tomography imaging procedures.
- Fee: $155 application, $155 renewal, every 2 years
- Credential: Completion of an approved CT course of study and current ARRT certification/registration in computed tomography
How it differs from the general license: New Hampshire issues CT as its own distinct state license category under RSA 328-J rather than folding it into the radiographer license; the statute lists computed tomography technologist as a separately enumerated credential requiring CT-specific certification. The reviewed statutory text did not impose an explicit prior radiographer license as a prerequisite (unlike MRI), so it reads as a standalone license.
MRI Technologist (Magnetic Resonance Technologist)
Divergence: separate license. Magnetic resonance imaging procedures (non-ionizing).
- Fee: $155 application, $155 renewal, every 2 years
- Credential: Completion of a radiography course of study plus additional MR education approved by the board, and current MR certification/registration
How it differs from the general license: Unlike most states, New Hampshire licenses MRI as its own state credential under RSA 328-J even though MRI uses no ionizing radiation. The magnetic resonance technologist license requires radiography coursework as a foundation plus additional MR-specific education and certification, making it a distinct license rather than a facility-credentialed post-primary.
Radiation Therapist
Divergence: separate license. Administration of ionizing radiation to human beings for therapeutic purposes.
- Fee: $155 application, $155 renewal, every 2 years
- Credential: Completion of an approved radiation therapy course of study and current certification from an approved organization (e.g., ARRT in Radiation Therapy)
How it differs from the general license: Radiation therapist is a separately enumerated license under RSA 328-J distinct from the diagnostic radiographer license, defined by therapeutic (not diagnostic) administration of ionizing radiation and requiring radiation-therapy-specific education and certification.
Nuclear Medicine Technologist
Divergence: separate license. Nuclear medicine and molecular imaging procedures using sealed and unsealed sources of radiation.
- Fee: $155 application, $155 renewal, every 2 years
- Credential: Completion of an approved nuclear medicine technology course of study and current certification/registration from ARRT (Nuclear Medicine) or the Nuclear Medicine Technology Certification Board (NMTCB), or other organization recognized by the executive director; age 18+; high school diploma or equivalent
How it differs from the general license: Nuclear medicine technologist is a separate state license under RSA 328-J distinct from the radiographer license, recognizing NMTCB certification in addition to ARRT and covering radiopharmaceutical-based imaging rather than external x-ray radiography.
Sonographer (Diagnostic Medical Ultrasound)
Divergence: separate license. Comprehensive set of diagnostic sonography procedures using ultrasound (non-ionizing).
- Fee: $155 application, $155 renewal, every 2 years
- Credential: Completion of an approved sonography course of study and current sonography certification/registration from an approved registry (e.g., ARDMS/ARRT)
How it differs from the general license: New Hampshire is one of the minority of states that issues a state license for diagnostic medical sonography even though ultrasound involves no ionizing radiation. The sonographer license is a distinct credential under RSA 328-J, separate from and not derived from the radiographer license.
Limited X-Ray Machine Operator
Divergence: limited-scope tier. Limited diagnostic radiography of specific parts of the human anatomy under direct supervision. Expressly prohibited from performing computed tomography, fluoroscopy, magnetic resonance imaging, mammography, radiation therapy, sonography, mobile imaging procedures, and imaging procedures using contrast media.
- Fee: $155 application, $155 renewal, every 2 years
- Credential: Permit limited to specific anatomical area(s) issued by the executive director under RSA 328-J; work performed under direct supervision of a licensed practitioner or licensed radiographer
How it differs from the general license: A reduced-scope permit below the full radiographer license, restricted to specific anatomical regions and requiring direct supervision. It cannot perform CT, fluoroscopy, MRI, mammography, radiation therapy, sonography, mobile imaging, or contrast studies, all of which a full radiographer (or the relevant modality license) may perform.
Medical Physicist
Divergence: no state credential.
How it differs from the general license: Medical physicist is not among the professions licensed by the NH Office of Professional Licensure and Certification under RSA 328-J (the Advisory Board of Medical Imaging and Radiation Therapy). Medical physics activity is instead addressed through DHHS Radiological Health radiation-control rules (e.g., authorized medical physicist provisions under He-P 4035) for radioactive-material/therapy programs, not as a personal professional license.
Specialties that follow the general New Hampshire license
These run under the general radiologic technologist license and need no separate state credential: Mammography.
Before you pay: confirm your modality
Within radiology, whether a modality needs its own state credential is not consistent, and it is the thing travelers most often get wrong. MRI, nuclear medicine, radiation therapy, sonography, and CT can each be a separate state license in one state, a facility credential checked against your ARRT registration in the next, and nothing extra in a third.
The divergences we verified for New Hampshire are above. What we cannot see is your specific assignment and the site you land at. Before you submit any application fee for an advanced modality, confirm with your recruiter whether New Hampshire issues a state credential for it or whether the facility handles that against your certification. We would rather you ask first than pay for something the role never required.
