Ohio Radiologic Technologist Licensing Guide

Most of the radiology family in Ohio 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.

CT Technologist

Divergence: specialty difference. Computed tomography is performed by a radiographer; OAC 3701-83-52 (freestanding diagnostic imaging centers) lists 'an individual licensed as a radiographer under Chapter 4773' as qualified to perform CT.

• Credential: Performed under the ODH Radiographer license (ORC Ch. 4773). No separate Ohio CT credential

Radiation Therapist

Divergence: separate license. Uses ionizing-radiation-generating equipment for therapeutic (cancer treatment) purposes on humans.

• Fee: $65 application, $45 renewal, every 2 years
• Credential: Distinct ODH radiologic license category, Radiation Therapist, under ORC Ch. 4773 / OAC 3701-72; eligibility typically via ARRT radiation therapy certification

How it differs from the general license: It is its own statutory license category separate from the diagnostic radiographer license, authorizing therapeutic delivery of ionizing radiation rather than diagnostic imaging.

Nuclear Medicine Technologist

Divergence: separate license. Prepares and administers radiopharmaceuticals and performs in vivo / in vitro detection procedures.

• Fee: $65 application, $45 renewal, every 2 years
• Credential: Distinct ODH radiologic license category, Nuclear Medicine Technologist, under ORC Ch. 4773 / OAC 3701-72

How it differs from the general license: It is its own statutory license category separate from the radiographer license, covering radiopharmaceutical administration and nuclear detection rather than x-ray radiography.

Sonographer (Diagnostic Medical Ultrasound)

Divergence: no state credential. Diagnostic medical ultrasound uses no ionizing radiation and is outside ODH radiologic licensure; Ohio does not license sonographers.

• Credential: No Ohio state license. Employers generally prefer or require ARDMS (or ARRT-S) certification, but the state issues no credential

How it differs from the general license: Unlike the radiographer license, sonography involves no ionizing radiation and is not regulated by ODH; there is no state credential at all and employers rely on national (ARDMS) certification.

Limited-Scope X-ray Operator (General X-ray Machine Operator / GXMO)

Divergence: limited-scope tier. Reduced scope: performs only specified body-site radiographs (chest/abdomen, extremities, skull/sinus, spine, podiatric radiography, bone densitometry) and only under direct supervision of a physician, podiatrist, mechanotherapist, or chiropractor. Cannot administer contrast or independently determine positioning/dosage like a full radiographer.

• Fee: $65 application, $45 renewal, every 2 years
• Credential: ODH General X-ray Machine Operator (GXMO) limited-scope license under ORC Ch. 4773 / OAC 3701-72; requires passing a state GXMO examination (separate from the ARRT radiography exam) and completion of competency-based clinical training modules
• CE: 12 CE credits per 2-year cycle, half the 24 credits required of full radiographer/NMT/radiation-therapist licensees

How it differs from the general license: It is a reduced-scope license below the full radiographer credential: limited to enumerated body sites, requires direct practitioner supervision, qualifies via a state GXMO exam rather than the ARRT radiography exam, and requires only 12 CE credits versus 24 for the full license.

Medical Physicist

Divergence: no state credential. Medical physics support (equipment surveys, dosimetry) is governed through facility/radiation-machine registration and certification standards rather than an individual ODH license.

• Credential: Ohio issues no general medical-physicist practitioner license. Narrow, role-specific certification requirements exist (e.g., a qualified medical physicist for CT/mammography under facility/radiation-machine rules, and federal MQSA mammography physicist surveyor qualifications), but these are not a personal state license comparable to a radiographer credential

How it differs from the general license: Unlike the radiographer license, Ohio does not license medical physicists as individuals; qualification is established through facility/radiation-control certification standards (e.g., ABMP/ABR board certification recognized in mammography and CT rules) rather than a state-issued personal license.

Credentialed by the facility, not the state

Ohio does not separately license these modalities. The hiring facility credentials them against your ARRT post-primary certification, and you still need the general radiologic technologist license underneath: MRI Technologist.

Specialties that follow the general Ohio 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 Ohio 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 Ohio 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.
