X-ray Equipment Inspection


The X-ray Program is responsible for inspecting facilities that use x-ray equipment and businesses that install x-ray equipment in Ohio.  Health physics inspectors travel throughout Ohio performing inspections on approximately 7,300 x-ray machines at 3,300 facilities annually.


Quality Assurance Items Reviewed at Inspection

-Current certificate of registration

-Regulations applicable to facility type

-Prior violations and corrective action review

-Notice-to-Employees postings

-Operator training

-Personnel monitoring

-Radiologic licenses

-Preventative maintenance

-Quality control tests: daily, monthly, quarterly

-Area radiation surveys

-X-ray equipment inventory

-X-ray equipment safe operating procedures

-X-ray equipment receipts, transfers and disposals

-Fluoroscopic equipment: tests by the medical physicist (radiation expert)

-Computed tomography equipment: tests by the medical physicist (radiation expert)

-Radiation therapy equipment: tests by the medical physicist (radiation expert)

-Any self-referral approval letters

-Any Food & Drug Administration (FDA) X-ray equipment variances


X-ray Equipment Tests Performed at Inspection

-Exposure, kVp and timer reproducibility

-kVp and timer accuracy

-Half-value layer

-Exposure switch position and function

-Entrance-skin exposure for examination

-Collimator and light field congruency

-Collimator beam size an alignment factors

-Safety interlocks


Inspection Time

It takes approximately 45 minutes to 1 hour to review the quality assurance documents and 15 to 20 minutes for every x-ray unit at small facilities.  Hospital inspections take 1-5 days based on facility size and the organization of their documents.
