Radiologic Licensure

Any individual who performs radiologic procedures on humans must hold a valid Ohio radiologic license, according to the Ohio Revised Code. Radiologic licenses are issued for the following categories: Radiographer, Nuclear Medicine Technologist, Radiation Therapist and General X-ray Machine Operator (GXMO).


The Radiologic Licensure program ensures standards of knowledge and skill for operators who apply radiation to humans for diagnostic or therapeutic purposes.  Through continuous enforcement, initiative and action, the program assures medical patients receive quality diagnostic imaging and services.

The program is funded by initial license application fees, renewal fees and educational provider fees.  The program has licensed approximately 17,000 operators, 110 educational facilities, and 180 continuing educational courses.
