Emerging Medical Technologies


This website provides licensing guidance for emerging medical technologies. The licensing guidance consists of general licensing considerations, specific radiation safety aspects of the emerging medical technology, and training and experience expectations for those authorized to use the emerging medical technology. This website may also help stakeholders who are developing new methods and technologies that may one day be used to treat medical patients. It also contains a record of the emerging medical technologies whose use has been evaluated for licensing by the NRC. Contact Us to submit medical-related inquiries.
