New Hampshire Radiologic Technologist Licensing Guide

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.
