The statement 'Dental imaging relies on radioactive materials' is

Dental imaging uses an external X-ray source to create images, not radioactive materials inside the body. An X-ray tube generates high-energy photons that pass through teeth and surrounding tissues; detectors or film capture how much radiation is attenuated to form the image. The radiation comes from an external source and is produced by the machine, not by radioactive decay within the patient. In contrast, nuclear medicine relies on radiopharmaceuticals that emit radiation from inside the body, which is not how routine dental radiographs are obtained. So the statement is false for standard dental imaging.
