Rad Tech License Requirements by State

39 states require a radiographer to hold the state's own license, certificate, permit or registration, by each state's official rules read 9 Nov 2026: Arizona, Arkansas, California, Connecticut, Delaware, Florida, Hawaii, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Montana, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Dakota, Ohio, Oregon, Rhode Island, South Carolina, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin and Wyoming. Alabama and Colorado issue none of its own, by its own rules. We have not yet read an official answer for Alaska, the District of Columbia, Georgia, Idaho, Missouri, Nebraska, North Carolina, Oklahoma, Pennsylvania and South Dakota; there, ask the state's radiation control program. Each state's rad tech page says what its rule asks for.

By the American Society of Radiologic Technologists' list of the states that regulate each modality, read 9 Nov 2026: CT in 12 (Arizona, the District of Columbia, Delaware, Florida, Kentucky, Massachusetts, Nebraska, New Hampshire, New Mexico, Rhode Island, South Carolina and Vermont); MRI in 8 (the District of Columbia, Florida, North Dakota, New Hampshire, New Mexico, Oregon, Washington and West Virginia); ultrasound in 5 (the District of Columbia, North Dakota, New Hampshire, New Mexico and Oregon). Elsewhere the employer usually asks for the ARRT or ARDMS credential in the modality.

In 34 of the 39 states with a state credential, the state's own rule names the ARRT exam or registration (Arizona, Arkansas, California, Connecticut, Delaware, Florida, Hawaii and Illinois and others). How a rad tech moves into CT or MRI.

Apply to that state's agency (its radiation control program or licensing board, named on the state's rad tech page) for its own credential before you start; many states base it on the ARRT exam or registration, as each state's page says. Where a state issues no credential of its own, the employer sets what it asks for.

8,701 radiologic technologist jobs are open on this board today in those 39 states, of 11,136 nationwide, each read from the employer's own careers site. A state in the table opens its rad tech jobs.
