General X-ray Machine Operator Educators

Rule 3701-72-03 of the Ohio Adminstrative Code includes a new educational model and curriculum requirement for the GXMO.  ODH has developed Guidance on Developing an Acceptable Syllabus for the General X-ray Machine Operator (GXMO) as well as an updated Application for Approval of a General X-ray Machine Operator Educational Program for GXMO educators. 

Continuing Educational Requirements

Any person applying to renew a license shall complete 12 classroom hours of continuing education (CE) courses in radiation safety approved by ODH. Applicants with multiple licenses may use the same 12 hours of CE for the renewal of each license.  

You must submit the following as evidence of meeting the continuing education requirements:

  • All licensees who hold a valid certification from the American Registry of Radiologic Technologists (ARRT) or the Nuclear Medicine Technologist Certification Board (NMTCB) may submit their current certification card, specific to the license category, as proof of meeting Ohio's continuing education requirements.


  • All licensees not certified by ARRT or NMTCB must submit a copy or copies of the certificate(s) verifying attendance of 12 classroom hours (one classroom hour is equivalent to 50 minutes of lecture and attendance) for continuing education courses in radiation safety approved by ODH.


  • All licensees certified by the ARRT or NMTCB, but are on CE probation or on retired status, may submit directed readings approved by the American Society of Radiologic Technologists (ASRT) or Society of Nuclear Medicine (SNM) in the subjects relating to radiation safety.

ODH accepts CE courses already approved by ASRT or the SNM for the subjects and number of classroom hours related to radiation safety.
