In many jurisdictions, including the United States, private citizens can legally own small quantities of depleted or natural uranium under specific regulatory exemptions, such as vintage items containing uranium glaze (like antique Fiestaware) or small mineral specimens for educational displays, provided they do not exceed strict mass limits set by nuclear regulatory agencies. However, possessing enriched uranium or large quantities of source material requires specialized federal licenses, rigorous security clearances, and strict compliance with national safety laws.
