Research and medicine uses many types of x-ray equipment including analytical, medical, dental, fluoroscopic, veterinary, cabinet systems and electron microscopes. All radiation-generating devices such as x-ray machines must be registered with the EH&S Radiation Protection Office (RPO).

Registration are reviewed in accordance with the procedures noted on the Radiation Authorizations program page. Once registered, the RPO issues a Permit that specifies the Authorized User (usually a Faculty Member), use restrictions, and approved machine operators. All operators, except for electron microscope users, must register with the RPO and receive training before using any x-ray equipment.
