National Source Tracking System (NSTS)

The NSTS is a major security initiative of the NRC. This highly secure, accessible and easy-to-use computer system tracks high-risk radioactive sources from the time they are manufactured or imported through the time of their disposal or export, or until they decay enough to no longer be of concern. This website has been developed to provide our stakeholders with the current status of program activities, tools and resources to aid in using the system, and mechanisms to provide direct feedback to us.
